Answer:

f(-4)=60 and g(-6)=17

Step-by-step explanation:

f(x)

Plug in -4 for x-values

  • 3(-4)^2 - 3(-4)

Square -4

  • 3(16) - 3(-4)

Multiply 3 by 16 and -3 by -4 then solve

  • 48+12=60

Simplify

  • f(-4)=60

g(x)

Plug in -6 for x

  • -3(-6)-1

Multiply -3 by -6

  • -3(-6)=18

Subtract 1

  • 18-1=17

Simplify

  • g(-6)=17

For this case we have the following functions:

[tex]f (x) = 3x ^ 2-3x\\g (x) = 3x-1[/tex]

We must find the value of the function [tex]f (x)[/tex] when [tex]x = -4[/tex], then:

[tex]f (-4) = 3 (-4) ^ 2-3 (-4)\\f (-4) = 3 * 16 12\\f (-4) = 48 12\\f (-4) = 60[/tex]

We must find the value of the function g (x) when [tex]x = -6[/tex], then:

[tex]g (-6) = 3 (-6) -1\\g (-6) = - 18-1\\g (-6) = - 19[/tex]

Answer:

[tex]f (-4) = 60\\g (-6) = - 19[/tex]
