Which represents the inverse of the function f(x) = 4x?
O h(x) = x + 4
• h(x) =x-4
H(x) = 3/4x
h(x) = 1/4x

4th option

Step-by-step explanation:

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

y = 4x ( divide both sides by 4 )

y = x

change y back into terms of x with x = h(x) , then

h(x) = x

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
