student	2,0	18,883	128	[]
volunteer	clsoe	18,883	129	[]
volunteer	it would be (0,-2)	18,883	130	[]
volunteer	do you see the pink	18,883	131	[]
student	oh yeah whoops	18,883	132	[]
volunteer	oh ok	18,883	133	[]
volunteer	so we have the y intercept	18,883	134	[]
volunteer	do you know how to find slope?	18,883	135	[]
student	rise over run	18,883	136	[]
volunteer	yup	18,883	137	[]
student	1	18,883	138	[]
volunteer	good job	18,883	139	[]
volunteer	so the equation of the new line	18,883	140	[]
volunteer	is y= x-2	18,883	141	[]
volunteer	alright now lets apply the formula	18,883	142	[]
volunteer	g(x) btw is the new line	18,883	143	[]
volunteer	let me simplfy that a bit for you	18,883	144	[]
volunteer	ok let me tell you what I did	18,883	145	[]
volunteer	so the orginal formula is g(x) = f(bx)	18,883	146	[]
volunteer	right	18,883	147	[]
student	yes for horizontal stretch	18,883	148	[]
volunteer	yup	18,883	149	[]
volunteer	we know g(x) = x-2	18,883	150	[]
volunteer	as g(x) is the new line	18,883	151	[]
volunteer	so i replaced the left side of the equation with x-2	18,883	152	[]
volunteer	and f(x) = 2x-4	18,883	153	[]
volunteer	but because b is inside the f(bx)	18,883	154	[]
volunteer	it only affects the x	18,883	155	[]
volunteer	so it becomes bx-4	18,883	156	[]
volunteer	does that sorta make sense	18,883	157	[]
student	uhh kinda	18,883	158	[]
volunteer	are you confused on the right side of the equation and how i did that?	18,883	159	[]
student	yea	18,883	160	[]
volunteer	yeah i kinda understand	18,883	161	[]
volunteer	uhh for now just bare with me on the horizantal stretch	18,883	162	[]
volunteer	lets try A it says it stretchs by a factor	18,883	163	[]
volunteer	of 2	18,883	164	[]
volunteer	which means b is 2	18,883	165	[]
volunteer	let me rewrite it for you i sorta messed up	18,883	166	[]
volunteer	scroll down	18,883	167	[]
volunteer	can you see it?	18,883	168	[]
student	yep	18,883	169	[]
volunteer	so for a	18,883	170	[]
volunteer	we see the scale factor of 2	18,883	171	[]
volunteer	plug in 2 to b	18,883	172	[]
volunteer	and tell me what the right side of the equaiton looks like	18,883	173	[]
volunteer	-4 is right btw	18,883	174	[]
volunteer	did you see what I did there	18,883	175	[]
student	yes i just got confused	18,883	176	[]
volunteer	since it tells us for a b = 2	18,883	177	[]
volunteer	oh that's alright	18,883	178	[]
volunteer	so what that look like	18,883	179	[]
volunteer	if you simplfy only the right side	18,883	180	[]
volunteer	yup	18,883	181	[]
volunteer	and that doesn't match the x-2	18,883	182	[]
volunteer	right	18,883	183	[]
student	right	18,883	184	[]
volunteer	yeah so the goal is to match the right side to the left side	18,883	185	[]
volunteer	so the left side should end up as x-2	18,883	186	[]
student	oh wait were trying to gt it to equal oh okay	18,883	187	[]
volunteer	yeah	18,883	188	[]
volunteer	now lets try b	18,883	189	[]
volunteer	we are told the factor is 1/2	18,883	190	[]
volunteer	tell me what the right side equation would look like	18,883	191	[]
volunteer	yup	18,883	192	[]
volunteer	now simplfy the right side a bit more	18,883	193	[]
student	this one is wrong	18,883	194	[]
volunteer	yup	18,883	195	[]
volunteer	so it has nothing to do with a horizantal stretch or shrinl	18,883	196	[]
volunteer	so lets look at the vertical stuff	18,883	197	[]
volunteer	the formula is g(x) = bf(x)	18,883	198	[]
volunteer	do you get how i came up with that equation	18,883	199	[]
student	scale factor times function	18,883	200	[]
volunteer	yup	18,883	201	[]
volunteer	so lets try c	18,883	202	[]
volunteer	scale factor of 2	18,883	203	[]
volunteer	tell me the final equation	18,883	204	[]
volunteer	on the right side	18,883	205	[]
student	4x-8	18,883	206	[]
volunteer	yup and it doesn't match right	18,883	207	[]
student	nope	18,883	208	[]
volunteer	we pretty much know it's d now	18,883	209	[]
student	so the answer is d	18,883	210	[]
student	okay alright	18,883	211	[]
volunteer	yeah	18,883	212	[]
volunteer	do you need help on 2?	18,883	213	[]
student	isnt it 10 < x <15	18,883	214	[]
volunteer	yeah don't forget the -	18,883	215	[]
volunteer	on the 10	18,883	216	[]
volunteer	but yeah	18,883	217	[]
student	okay yay	18,883	218	[]
volunteer	anything else?	18,883	219	[]
student	i thinkkkk i got it	18,883	220	[]
volunteer	alright then Ill cya then	18,883	221	[]
student	goodnight!	18,883	222	[]
volunteer	u too	18,883	223	[]
student	I need help from#2 and down	17,114	0	[]
volunteer	Is there an accompanying graph or something for this problem?	17,114	1	[]
student	no	17,114	2	[]
student	thats just all thats on the paper	17,114	3	[]
