Question

True or Falus

The Inverse of f(x) = 2x - 10 is f^ -1 (x) = 1/2 x +5

Answer 1

y = 2x - 10
y + 10 = 2x
x = y + 10
------
2

x = 1/2y + 5

Answer 2

now switch the y for x

Answer 3

so the inverse = 1/2x + 5

Answer 4

you can check by f(f^-1)=x. therefore, f^-1 is inverse.
I mean f(f^1)= 2(1/2x +5) -10 =x therefore,1/2 x +5 is inverse of 2x -10

Answer 5

Its True Thanks for your help everyone
