Question

Find the value of f(-3).
y = f(x)

Answer 1

y = -3

Explanation:

Look at the graph and align the x-factor to the y-factor. Also, if y = f(x) and f(x) = -3, then y = -3.

Answer 2

The value of f-3) is 3.

`f(x) = (x + 2)(x + 6).`

The value of f(-3),

We substitute -3 for x in the expression

`f(-3) = (-3 + 2)(-3 + 6)`

`f(-3) = (-1)(3)`


`f(-3) = -3`

Therefore, the value of f(-3) is -3.
