Question

I need help please.

Answer 1

4. A biologist studied the populations of white-sided jackrabbits and black-tailed jackrabbits over a 5-year period. The biologist modeled the populations, in thousands, with the following polynomials where x is time, in years.

White-sided jackrabbits: 5.5x2 – 9.2x + 6.9
Black-tailed jackrabbits: 5.5x2 + 9.9x + 1.3

What polynomial models the total number of white-sided and black-tailed jackrabbits?

(1 point)
11x2 + 0.7x + 8.2
11x2 – 0.7x + 8.2
11x2 – 0.7x – 8.2
–11x2 + 0.7x – 8.2
