F(x)= -2x-4 (x=3) substation

the answer is -10

Step-by-step explanation:

f(x)= -10

Step-by-step explanation:

When you substitute x with 3 you multiply 3 and -2 and get -6 and when you subtract 4 from -6 you get -10

the answers c

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
