Question

if f(x) = 2x + 3 and g(x) = x^2, then g[f(-3)] = ?

Answer 1

Ok, first solve what f(-3) = 2x + 3 would be.
Plug in -3 wherever there is an x

Answer 2

f(-3) = 2x + 3
= 2(-3) + 3
= -6 +3
= -3

Answer 3

Therefore, g[f(-3)] is equal to g (-3)
(because f(-3) = -3)

Answer 4

g(-3) = x^2
= (-3)^2
= 9

Answer 5

thank you
