Question

What is the inverse of the function f(x) = 2x – 10?

Answer 1

i think we have to do integration
2x-10
2×(-10) x^2/2
-20x^2/2
-10x^2

Answer 2

Given Function,
f (x) =2x-10
let y= f (x) = 2x-10
y = 2x-10
Interchanging x and y .

x= 2y-10
2y= x+10
y =( x+10)/2
y= x/2 + 5
is required inverse
