The table below shows some inputs and outputs of the invertible function f etc

Snowcat [4.5K]

Answer:

$(a)\ f^{-1}(-15) = -6$

$(b)\ f^{-1}(4) + f(9)=0$

Step-by-step explanation:

Given

The attached table

$(a)\ f^{-1}(-15)$

This represents an inverse function.

So, we look into x row for its value.

i.e.

$f^{-1}(-15) = -6$

$(b)\ f^{-1}(4) + f(9)$

Just like (a)

$f^{-1}(4) = -11$ ---- by looking into the x rows

$f(9) = 11$

So:

$f^{-1}(4) + f(9)=-11 + 11$

$f^{-1}(4) + f(9)=0$

Which equation is a function of x? A. x=5 B. x=y2+9 C. x2=y D. x2=y2+16

My name is Ann [436]

A function is a process or a relation that associates each element x of a set X to a single element y of another set Y.

A. The equation $x=5$ represents vertical line. This is not a function, because one element x=5 is associated to all (not one) elements of $y\in (-\infty,\infty).$

B. The equation $x=y^2+9$ represents parabola that goes in positive x-direction. This is not a function, because each $x>9$ is associated to two different y. For examlpe, when x=10, then $y_1=1,\ y_2=-1.$
