Question

The two functions t(x) and v(x) are defined below.
t(x)=6x-1
v(x)=x^2+2
Evaluate the composition of functions v(t(4))

Answer 1

Answer 2

@zepdrix

Answer 3

v(x) = x^2 + 2
so
v[ t(x)] = [t(x)]^2 + 2
= [ 6x-1]^2 + 2

Answer 4

i dont really understand

Answer 5

uh where did the 6x come frome

Answer 6

@agent0smith could you help make it clearer

Answer 7

The 6x came from t(x)...

t(x)=6x-1
v(x)=x^2+2

v[ t(x) ] = [ t(x) ]^2 + 2
= [ 6x-1 ]^2 + 2

Answer 8

but how about the 4

Answer 9

v(t(4))

Answer 10

v[ t(x) ] = [ 6x-1 ]^2 + 2

v[ t(4) ] means plug in x=4
