If 8(x) is the inverse of f(x) and f(x) = 4x + 12 what is g(x) ?
1 answer:
Answer:
(y-12)/4
Step-by-step explanation:
If g(x) is the inverse of f(x)
and f(x) = 4x + 12
f⁻¹(x) = g(x)
let f(x) be represented as y
f(x)
= y
y = 4x + 12
subtract 12 from both sides
y-12= 4x
divide both sides by 4
(y-12)/4 = x
so f ⁻¹ (y)= (y-12)/4 so g(x) = (x-12)/4

Step-by-step explanation:
5x + 5 = 4x + 16 ( being alternate angles)
5x - 4x = 16 - 5
x = 11
