B. 19
C. -9
D. -19

I'm completely lost

Answer 1

replace x = 2 into f(x)=7x-5

f(2)=7(2)-5 = 14 -5 = 9

answer is A. 9

Answer 2

Answer: A)
`9`

Explanation:

Here the given function,

`f(x) = 7 x -5`

At x = 2,

By putting this value of x in the given function,

`f(2) = 7* 2 -5`

`f(2) = 14 - 5`

`f(2) = 9`

Thus, For
`x=2`,

`f(x) = 9`

Therefore, Option A is correct.
