Question

You have two exponential functions. One function has the formula g(x) = 3 x . The other function has the formula h(x) = 2-x. Which option below shows the graph of k(x) = g(x) - h(x)?

Answer 1

k(x) = 4x - 2

Please refer attachment for the graph.

Explanation:

Given :

g(x) = 3x

h(x) = 2- x

k(x) = g(x)-h(x)

k(x) =3x -(2-x) = 3x -2 +x =4x -2

∴k(x) = 4x - 2
