If p(x) = 2x2 – 4x and q(x) = x – 3, what is mc007-1.jpg? 2x2 – 4x + 12 2x2 – 16x + 18 2x2 – 16x + 30 2x2 – 16x + 15

Rainbow [258]

P(x) = 2x² - 4xq(x) = x - 3
To find the answer, we plug q(x) into p(x):
p(q(x)) = 2(x - 3)² - 4(x - 3)p(q(x)) = 2(x² - 6x + 9) - 4x + 12p(q(x)) = 2x² - 12x + 18 - 4x + 12p(q(x)) = 2x² - 16x + 30
The third option is correct.
