Question

SHOW WORK: Evaluate f(-2) with f(x)=3x+1 *

Answer 1

Explanation:

`{:}\longrightarrow`
`\sf f (x)=3x+1`

`{:}\longrightarrow`
`\sf f (-2)=3 (-2)+1`

`{:}\longrightarrow`
`\sf f (-2)=-6+1`

`{:}\longrightarrow`
`\sf f (-2)=-5`

Answer 2

f(2) = 7

Explanation:

Solve for f(-2) in f(x) = 3x + 1

x = -2

Plug in -2 for x in the equation:

f(2) = 3(2) + 1

Remember to follow PEMDAS. First, solve the multiplication, then add:

3 * 2 = 6

6 + 1 = 7

f(2) = 7 is your answer.
