Question

Find the inverse of the function f(x)=2/5x+10

Answer 1

Explanation:

f(x)=2/5x+10

let y =f(x)

y=2/5x+10 calculate : x

2/5 x = y - 10

2x = 5(y-10)

x = 5/2(y-10)

x = 5/2y -25

the inverse of the function f(x)=2/5x+10 is : g(x) = 5/2x -25

Answer 2

1. Answer: y=5/2x25 Step-by-step explanation: First you need to switch f(x) to y --> y=2/5x+10 Next you swap the x's and y's --> x=2/5y+10 Then you solve for y --> x-10=2/5y 5x-50=2y 5/2x-25=y
