If f(x) = x + 3 and g(x) = −4x − 1, find g[f(4)]

Question

anonymous · Answer

for these problems, if you haven't caught on yet you have to plug the 4 into the question of f then into the equation of g
$$f(4)=4+3=7, g(f(4))=-7(4)-1=-29$$

-29 est le anser

hero · Answer

f(x) = x + 3
g(x) = −4x − 1

   g(f(x)) 
= -4(f(x)) - 1
= -4(x + 3) - 1
= -4x - 12 - 1
= -4x - 13

   g(f(4))
= -4(4) - 13
= -16 - 13
= ?

marvin gimme my medal back!!

anonymous · Answer

you have to plug four into f and u get seven and then plug 7 into g

hero · Answer

For these problems, find g(f(x)) first. Then plug in x = 4 to get g(f(4))
