Question

Let f(x) = 4x2 and g(x) = 7x. Determine the domain of the composite function and then find the composite function.
(f g)(x)

Answer 1

Domain all real numbers.

put 7x into f(x) every where there is an x

f(x) = 4(7x)^2
f(x) = 4*49x^2
f(x) = 196x^2

Answer 2

bah all of those problems today arnt rite. i worked and worked on em but there not rite thanx tho
