These definitions are mathematically loose (that means a mathematician would pull his or her hair out but a normal person might understand them).
Graph of a function
The graph of a function f is the set of all ordered pairs ( x, f(x) ) where x is in the domain of f.

$y=-\sqrt{x-3}-2$
RECALL: (i) $y=-f(x)$ involves a reflection about the x-axis of the parent function $y=f(x)$. (ii) $y=f(-x)$ involves a reflection about the y-axis of the parent function $y=f(x)$. (iii) $y=af(x)$ involves either a vertical compression by a factor of $a$ of the paren... |

A surd is an expression that includes a square root, cube root or another root symbol. Surds are used to write irrational numbers precisely – because the decimals of irrational numbers do not terminate or recur, they cannot be written exactly in decimal form.
