Exam 5: Polynomials, Polynomial Functions, and Factoring

Solve the problem. -The following table shows the number of speeding tickets issued in a certain state for the past five years. Year Speeding Tickets Issued 1 2500 2 2544 3 2601 4 2637 5 2690 The polynomial function f(x) = -0.63x3 + 0.55x² + 61.16x + 2439.2 models the number of speeding tickets issued over the past five years. Use this function to predict the number of speeding tickets issued in year 15. Round to the nearest whole number.

Use the FOIL method to multiply the binomials. Assume any variable exponents represent whole numbers. - $( x + 7 y ) ( x + 2 y )$

Find the product. Assume all variable exponents represent whole numbers. - $( x y - 7 ) \left( x ^ { 2 } y ^ { 2 } + 2 x y + 6 \right)$

Use the graph to estimate the average number of minutes a woman exercised per week if her average monthly weight loss was 4.4 pounds. A) 115 min B) 120 min C) 135 min D) 127 min Answer: B Determine whether the graph shown is the graph of a polynomial function. -

Multiply using the rule for the product of the sum and difference of two terms. Assume any variable exponents represent whole numbers. - $( 12 x - 11 y + 3 ) ( 12 x - 11 y - 3 )$

Find the product. Assume all variable exponents represent whole numbers. - $( x + 3 ) \left( 6 x ^ { 2 } + 2 x + 5 \right)$

Multiply the monomial and the polynomial. Assume any variable exponents represent whole numbers. - $4 x ^ { 2 } y \left( - 4 x ^ { 2 } y ^ { 4 } - 8 x y ^ { 3 } + 6 \right)$
