5) determine whether the function has an inverse function. if it does, find the inverse function.
a(x) = (x + 4)², xz4
a) f(x) = √x + 4
b)f'(x)=-(x +4)2
c) f'(x) = (x + 4) 2
d) ) = √x - 4
e) no inverse

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
