Plz help!

For f(x) = −2x + 12, find f(x) when x = −3.

Af(−3) = 6
Bf(−3) = −18
Cf(−3) = 18
Df(−3) = 20

f(p)=7/11p-10

Find f(77).

Af(77) = 59
Bf(77) = 49
Cf(77) = 67
Df(77) = 39

Verified Answer :

 f(x) = −2x + 12, find f(x) when x = −3.

replace x = -3 then

f(-3) = (-2)(-3) + 12

        = 6 + 12

        =18

Answer is C) f(−3) = 18

f(p)=7/11p-10 Find f(77)

f(77) = 7/11 (77) - 10 (cancel out 77 and 11)

        = 7 * 7 - 10

        = 49 -10

        =39

       Answer is D) f(77) = 39
