The table below shows some inputs and outputs of the invertible function f with domain all real numbers. NEED HELP NOW!!!!!

Answer 1

Answer:

( 1 ) $f^{-1}(f(576)) = 576$,

( 2 ) $f^{-1}(-7)+f(-7) = 13$

Step-by-step explanation:

Taking the function and it's inverse, it should be the following property -

$f^{-1}(f(x))= x$ - this therefore makes the functionality " $f^{-1}(f(576))= x$ " equivalent to 576 itself.

For this second part here let's consider the portion " $f(-7)$ " firstly. As you can see from the table, - 7 should represent the x - value, hence $f(-7) = 7$. Now for this second bit here, we have to take the inverse - making the what should have been the x - value, now the f( x ) value. Therefore, $f^{-1}(-7) = 6$.

This would make $f^{-1}(-7)+f(-7)$ = $7+6$ = 13.
