How to find f(-4) f(-2) and f(3)

Answer 1

f(4) = -4/3

f(-2) = 4

f(3)= 1

Explanation:

To find the values for f(x), we must substitute each value of x into the equation (remember to look at the domains).

f(-4):

Since -4≠-2, we substitute it into the equation:

`-(1)/(3) (-4)^(2)+4`

This gives us -4/3

f(-2)

According to the domain, if x = -2, then f(-2) = 4

f(3)

`-(1)/(3) (3)^(2)+4`

This gives us 1
