If p times x is equal to 2 x squared minus 4 x and q times x is equal to x minus 3 , what is open paren p circ q close paren times x ?

To find (p ∘ q)(x), substitute q(x) = x − 3 into p(x) = 2x² − 4x. This gives 2(x − 3)² − 4(x − 3) = 2x² − 12x + 18 − 4x + 12 = 2x² − 16x + 30. The correct choice is C, 2x² − 16x + 30.
