If (8,-2) is on the graph of f(x), which point must be on the graph of the inverse funtion f^-1(x)?

(-2,8)

Step-by-step explanation:

If a function is f:R→R is defined as

then its inverse is defined as

It is given that (8,-2) is on the graph of F(x).

x-coordinate = 8, y-coordinate = -2

Interchange the coordinates to find the point which lies on the inverse function F⁻¹(x).

x-coordinate = -2, y-coordinate = 8

It means (-2,8) must be on the graph of the inverse function F⁻¹(x).

30

step-by-step explanation:

times by times

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
