What is the inverse of the function f(x) = 2x – 10?
h(x) = 2x - 5
h(x) = 2x + 5
"
h(x)=2x-5
o ncx) = {x+5

Respuesta :

Answer:

see explanation

Step-by-step explanation:

let y = f(x) then rearrange making x the subject

y = 2x - 10 ( add 10 to both sides )

y + 10 = 2x ( divide both sides by 2 )

[tex]\frac{y+10}{2}[/tex] = x

Change y back into terms of x

[tex]f^{-1}[/tex] (x) = [tex]\frac{x+10}{2}[/tex]
