Question

G(x) = 4x2 – 3x + 2, find g(2a).

Answer 1

Answer:

g(2a) = 16a^2 - 6a + 2

Step-by-step explanation:

Replace every occurrence of x in g(x) = 4x^2 – 3x + 2 with (2a); it's best to use parentheses here.

Then g(2a) = 4(2a)^2 - 3(2a) + 2

                  =  4(4a^2) - 6a + 2

                   =  16a^2 - 6a + 2 (answer)
