Question

What is the inverse of the function f(x) = 1/4x – 12?
a) h(x)= 48x - 4
b) h(x)= 48x + 4
c) h(x)= 4x - 48
d) h(x)= 4x + 48

pls help :3

Answer 1

this is the answer
hope it will help u

Answer 2

Inverse of given function f(x) = (1/4)x - 12 is option

(d) h(x) = 4x + 48

• Let f(x) = y

• To get the inverse of given function we have to convert x in form of a function of y and then replace x with h(x) and y with x

then y = (1/4)x - 12

y + 12 = (1/4)x

4(y + 12) = x

• let x = h(x)

then

h(x) = 4x + 48

• Hence, the answer is (d)
