Question

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

Oh(x) = 2x-5
O h(x) = 2x + 5
O h(x) =
X-5
h(x) = 3x -
h(x) = 2x +
x5
o hx

Answer 1

Last Option

Explanation:

Step 1: Write function

f(x) = 2x - 10

y = 2x - 10

Step 2: Swap

x = 2y - 10

Step 3: Solve for y

x + 10 = 2y

y = x/2 + 5

f⁻¹(x) = x/2 + 5
