The equation c=1.5x + 89.42 can be used to estimate the cost c of a holiday dinner for 10 people x years after 2000. Determine in what year the cost of a dinner for 10 people will be $116.42.

Lassify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3) linear function; linear term: −21x; constant term: −6 linear function; linear term: −18x2; constant term: −6 quadratic function; quadratic term: 6x2; linear term: 24x; constant term: −6 quadratic function; quadratic term: −18x2; linear term: −21x; constant term: −6
