3. dorothy has decided to raise rabbits but has been warned that the number of rabbits she will have will grow very quickly. dorothy started out with 20 rabbits and the function y = 20 • 2.3x models the number of rabbits she will have after x months. which graph represents this function? (1 point)graph graph graph graph 4. multiply. give your answer in standard form. (3n2 + 2n + 4)(2n – 1) (1 point)6n3 + n2 + 6n – 4 6n3 + 7n2 + 6n – 4 6n3 – n2 + 10n – 4 6n3 + n2 + 10n – 4 5. multiply. (2n + 2)(2n – 2) (1 point)4n2 – 4 4n2 – 4n – 4 4n2 + 2n – 4 4n2 + 4n – 4 6. the area of a rectangular painting is given by the trinomial x2 + 4x – 21. what are the possible dimensions of the painting? use factoring. (1 point)(x + 7) and (x + 3) (x – 7) and (x + 3) (x – 7) and ( x – 3) (x + 7) and (x – 3) 7. graph the function and identify the domain and range. y = –6x2 (1 point)graph domain: (–∞,∞) range: y ≤ 0 graph domain: (–∞,∞) range: y ≥ 0 graph
