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

it's inverse is:

f(x)^-1 = (x+10)/2

Step-by-step explanation:

f(x)= 2x -10

y= 2x -10 [ let f(x) be y]

interchange value of x and y

x=2y -10

(x+10) = 2y

y=(x+10)/2

f(x)^-1 = (x+10)/2

The inverse f-1(x) = (x + 10)/ 2.

Step-by-step explanation:

Let y = 2x - 10

Now make x the subject:

y = 2x - 10

2x = y + 10

x = (y + 10) / 2

Replace y by x and x  by f-1(x)  ( the inverse):

f-1(x) = (x + 10) / 2
