restrict the domains of quadratic functions and absolute value functions, because these functions are

functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are

functions, so their domains

to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
Answer:
Are there an A,B,C, and D<?
Step-by-step explanation:
Answer:

Step-by-step explanation:

- With the equation's current format, we will have trouble solving with all these fractions. Especially the fraction
is very difficult to deal with, so my first step would be:

- If we multiply both sides by this number, we will be able to get rid of the messy fraction on the right side as well as remove the fraction on the left side. Like so:
- <em>I put the
I multiplied onto each side in fraction form simply for clarity. You do not need to do this.</em>

- After this point, let's put our variable,
, onto one side of this equation and any other integers on the other by adding and subtracting them from both sides.

- Now we divide so that
is isolated, and we are done.

Answer:
63
Step-by-step explanation:
7*9 = 63
-7*-9 = 63
negative*negative = positive
negative*negative*negative = negative
Even negative numbers are always positive on multiplication odd negative numbers on multiplication are always negative
