Answer
Explanation:
Step1: Recall inverse function reflection
The graph of an inverse function of a function ( y = f(x) ) is the reflection of the graph of ( f(x) ) across the line ( y = x ). So the first drop - down (for the line of reflection) should be "line ( y = x )".
Step2: Determine if ( g(x)=x^{2}-2 ) is one - to - one
A function has an inverse that is also a function if and only if the original function is one - to - one (passes the horizontal line test). The function ( g(x)=x^{2}-2 ) is a parabola opening upwards with vertex at ( (0, - 2) ). It does not pass the horizontal line test (for example, ( g(2)=2^{2}-2 = 2 ) and ( g(-2)=(-2)^{2}-2 = 2 ), so two different inputs give the same output). So the inverse of ( g(x) ) will not be a function. To check if a relation is a function, we use the vertical line test. For the inverse of ( g(x) ), if we consider the relation, when we reflect ( g(x) ) over ( y = x ), the inverse relation will not pass the vertical line test (because the original function did not pass the horizontal line test). So the second drop - down (Is the inverse a function?) should be "is not", and the third drop - down (reason related to vertical line test) should be "does not pass the vertical line test" (because for a relation to be a function, every vertical line must intersect the graph at most once).
Answer:
- The graph of the inverse of ( g(x) ) is the reflection of the graph of ( g(x) ) across the (\boldsymbol{\text{line } y = x}).
- The inverse of ( g(x) ) (\boldsymbol{\text{is not}}) a function because for each input of the inverse of ( g(x) ) there (\boldsymbol{\text{does not pass the vertical line test}}) (i.e., there are inputs with more than one output).
