  1. Identify Functions: Identify the given functions:\newlineq(x)=2xq(x) = 2x\newlinec(x)=2x2+9xc(x) = -2x^2 + 9x
  2. Multiply Functions: Multiply the functions q(x)q(x) and c(x)c(x):
    (qc)(x)=q(x)c(x)=(2x)(2x2+9x)(q*c)(x) = q(x) * c(x) = (2x) * (-2x^2 + 9x)
    = 2x2x2+2x9x2x * -2x^2 + 2x * 9x
    = 4x3+18x2-4x^3 + 18x^2
