If f(x) =27 and x=9 , what is the constant of variation (k) for this function?
hint: use f(x)=kx and solve for k.
give your answer as a number.

Consider the polynomials given below. p(x) = x4 + 3x3 + 2x2 – x + 2 q(x) = (x3 + 2x2 + 3)(x2 – 2) determine the operation that results in the simplified expression below. 35 + x4 – 573 - 3x2 + x - 8 a. p+q b. pq c.q-p d. p-q
