What is the inverse function of the function f(x)=4x+8

Step-by-step explanation:

the inverse function of the function f(x)=4x+8

To find inverse function do the following steps

step 1:  Replace f(x) with y

y = 4x+8

step 2: Replace x with y and y with x

x= 4y +8

step 3:  solve for y

x = 4y +8

Subtract 8 from both sides

x-8 = 4y

divide by 4 on both sides

Divide each term by 4

Step 4 : Replace y with f^-1(x)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
