Answer:

[tex]h(x) = 57(0.8)^x[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 32(0.8)^x[/tex]

[tex]g(x) = 25(0.8)^x[/tex]

Required

A function that represents the total resale value of the two vehicles

To do this, we simply add up the functions

[tex]h(x) = f(x) + g(x)[/tex]

[tex]h(x) = 32(0.8)^x + 25(0.8)^x[/tex]

Factorize

[tex]h(x) = (32 + 25)(0.8)^x[/tex]

[tex]h(x) = 57(0.8)^x[/tex]
