Question

Let f(x)= -2x+12 and g (x) =4(3)^x-2. Find the value of x so that f(x)=g(x)

A. 1
B. 10
C.-2
D.12

Answer 1

Answer: A. 1


Step-by-step explanation:

Plug 1 into the equation for x.

f(1) = -2(1) + 12
g(1) = 4(3)^1 - 2

f(1) = 10
g(1) = 10

Both function got the same answer which mean that they are equal and is true. So A is the correct answer.
