Question

If f(x) = 7x2 – 3 and g(x) = 5x, which expression is equivalent to [g o f](2)??

Answer 1

plug 2 in place of x in f(x) same as f(2) and solve.
take the value you get out of f(2) and replace x in g(x) for answer

Answer 2

7(2)^2 - 3 =
plug that result into the equation for g(x) ..

Answer 3

plug 2 into the first function of f(x)

Answer 4

2 into the, into the g
g(f(2))

Answer 5

what is 7(2)^2-3
