Respuesta :

g(x) - f(x) = 3x - 9 -(5x - 1) = 3x - 9 -5x + 1 = -2x - 8

Answer:  The required value of g(x) - f(x) is [tex]5x-3^x+8.[/tex]

Step-by-step explanation:  We are given the following two functions :

[tex]f(x)=5x-1,\\\\g(x)=3^x-9.[/tex]

We are to find the value of g(x) - f(x).

We have

[tex]f(x)-g(x)\\\\=(5x-1)-(3^x-9)\\\\=5x-1-3^x+9\\\\=5x-3^x+8.[/tex]

Thus, the required value of g(x) - f(x) is [tex]5x-3^x+8.[/tex]
