Question

The functions fand g are defined as follows. 3 f (x) = 3x - 5 g(x) = – 4x-1

Find f(-2) and g(?).

Simplify your answers as much as possible.

f(-2)= []
g(2)= []​

Answer 1

`\huge \boxed{\mathrm{f(-2)=-11 }} \\\\\\ \huge \boxed{\mathrm{g(2)=-9 }}`

Explanation:

`\sf f (x) = 3x - 5 \\\\\\ g(x)=-4x-1`

The input value or x value for f(-2) is -2.

`\sf f (-2) = 3(-2) - 5 \\\\\\ \sf f (-2) = -6 - 5 \\\\\\ f(-2)=-11`

The input value or x value for g(2) is 2.

`\sf g(2)=-4(2)-1 \\\\\\ g(2)=-8-1 \\ \\ \\ g(2)=-9`

Answer 2

see below

Explanation:

f (x) = 3x - 5

g(x) = – 4x-1

f(-2)=

Let x =-2

f(-2) = 3*-2 -5 = -6-5 = -11

g(2)=

Let x=2

g(2) = -4(2) -1 = -8-1 = -9
