Question

what is f(g(x)) if f(x)=3x2-x+4 and g(x)=2x+1 ?

Answer 1

f(g(x)) just mean that you are plugging in g(x) in place of x in f(x)

Answer 2

3(g(x))^2 -g(x) +4

Answer 3

what is f(x) equal when x = g(x) ?

Answer 4

so its 3(2x+1)-2x+4 ?
Im confused..

Answer 5

you did not plug in g(x) into second x

Answer 6

i don't understand this, could you just do it and explain the steps ?:l

Answer 7

Are you trying to say to plug in the 3 to the x's ? or plug in the f(X) equation ? into the x's ?

Answer 8

3(g(x))^2 -(g(x))+4

Answer 9

so we plug in g(x)
