Use the functions given by $f ( x ) = \frac { 1 } { 8 } x - 3$ and $g ( x ) = x ^ { 2 }$ to find the value $\left( g ^ { - 1 } \circ g ^ { - 1 } \right) ( - 4 )$
A)16
B)-16
C)32
D)The value does not exist.
E)-32

Quizplus · Accepted Answer

The function $g(x) = x^2$ is not one-to-one, so it does not have an inverse over all real numbers. Therefore, $g^{-1}$ does not exist for all values, including -4.
