Question

What values of x make up f(x)=3x+1 equal to g(x)=3^x+1? 0, 1, 2, 3 select all that apply

Answer 1

Let us plug-in the values of x to know

> x = 0

f(0) = 3(0) + 1 = 1

g(0) = 3^0 + 1 = 2

> x = 1

f(1) = 3(1) + 1 = 4

g(1) = 3^1 + 1 = 4

> x = 2

f(2) = 3(2) + 1 = 7

g(2) = 3^2 + 1 = 10

> x = 3

f(3) = 3(3) + 1 = 10

g(2) = 3^3 + 1 = 28

Therefore the only answer is:

1
