Question

A fiction is shown f(X) = 7-4x what is the value of f(-5)

Answer 1

Explanation:

To find the value of f(-5) in the function f(x), just put '- 5' into the function where 'x' is:

f(x ) = 7 - 4x

f(-5 ) = 7 - 4 (-5) = 7 + 20 = 27

Answer 2

`f( - 5) = 27`

Explanation:

Hello!!!

Given expression

`f(x) = 7 - 4x`

to find f(-5), substitute -5 in the position of x.

`f( - 5) = 7 - 4( - 5)`

Multiply -4 by -5 gives +27

`f( - 5) = 7 + 20`

Hope it helps!!!

add 7 and 20

`f( - 5) = 27`
