The inverse of f(x) is a function. true or false ?

The answer is True

Step-by-step explanation:

we know that

The function f(x) is a vertical parabola open downward

so

The equation of f(x) into vertex form is equal to

where

(h,k) is the vertex of the parabola

Let

Exchanges the variables x for y and y for x

Isolate the variable y

the coefficient a is negative

Let

------> inverse of the function f(x)

therefore

The inverse of f(x) is a function

my answer got deleted but it's a

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
