Question

Choose the best description of how to calculate f[g(−2)] if f(x) = 13x2 and g(x) = 7x − 5.

Calculate g(−2), plug the result into f(x) and simplify.

Calculate f(−2) and g(−2), then mulitply them together.

Calculate f(−2) and g(−2), then write the results as an ordered pair.

Calculate f(−2) and g(−2), then subtract them.

Answer 1

f[g(−2)]

you want to do the function for g(-2)
but because g(-2) is all in brackets, this means that when you come to the function f
your value to stick into f is the value you get when doing g(-2)
so you are doing g(-2) then sticking the result into f(x)

Answer 2

so D?

Answer 3

no A

Answer 4

oh ok lol
