Answer 1

Given:

f(x) = 3x + 2

To Find:

f(5)

Answer:

C. 17

Explanation:

Evaluate 3x + 2 where x = 5:

`\longrightarrow` 3 × 5 + 2

3 × 5 = 15:

`\longrightarrow` 15 + 2

15 + 2 = 17:

`\longrightarrow` 17

Answer 2

Option C

Explanation:

`f(x)=3x+2\\\\f(5)=3(5)+2\\\\f(5)=15+2\\\\\boxed{f(5)=17}`

Hope this helps.
