Does anyone understand this? If f(x) = 4x + 1 and g(x) = x2 – 2x + 1, what is f(g(x)) ? 4x2 – 8x + 5 4x2 + 2x + 2 x2 + 2x + 2 x2 – 2x + 2

OpenStudy (anonymous):

f(g(x)) meanign plug the value of g(x) in f(x)

OpenStudy (anonymous):

f(g(x))=4(x2-2x+1)+1 and solve!

OpenStudy (anonymous):

would that be, 8x-8x+4+1

OpenStudy (anonymous):

? sorry i dont get it

OpenStudy (anonymous):

4x^2-8x+5

OpenStudy (anonymous):

u just plug the g(x) value in f(x) fiction. Meaning wherever you see x in f(x) plug the value of g(x)

OpenStudy (anonymous):

why is it to the 2nd power?

OpenStudy (anonymous):

what do u mean by 2nd power?

OpenStudy (anonymous):

the 4x^2
