use mean value theorem:
f(x)= 7- 2^x, [0,4], c=?
• Calculus - ,
f(4) = -9
f(0) = 6
so, we want f'(c) = -15/4
f'(x) = -ln2 2^x
-15/4 = -ln2 2^c
15/(4ln2) = 2^c
ln(15/ln16) = c ln2
c = ln(15/(4ln2))/ln2 = 2.4356

With some betting sites odds, certain games are priced differently than risking \$1.10 to win \$1.00 (which is called -110 odds). For example, you might see the Giants priced at -105 and +7 in a game against the Jets. Now, you only have to risk \$1.05 to win \$1.00.

Hey guys
For the partial fraction:
$\frac{2x^2 + x + 6}{x^2 -4}$
How exactly does it become:
$2 + \frac{4}{x-2} - \frac{3}{x+2}$
I have no clue how the "2" appears.
