a) f "(1) si f(x) = -3x² - 5x+7 b) f(4) si f(x) = x² + x² −x³

Determine the domain of the following function: f(x) Vx + 7 x – 3 Ox> - 7 and z + 3 Or3 and z - 7 Or+3 Or+0 and z + - 7 Or<7 and r 3

Evaluate the following function at 2, -2, 0, and z. 2(2) Q(-2) 20) 22) Q (z) 2 Edit

A bird population can be modeled by f(x) = x³ - 61x² + 860x + 2200, where x = 1 corresponds to June 1, x=2 to June 2, and so on. Find the days when f estimates that there were 3000 birds. Select the correct choice below and fill in the answer box(es) within your choice. A. The bird population equals 3000 on June and July (Type whole numbers. Use a comma to separate answers as needed.) OB. The bird population equals 3000 on June (Type a whole number. Use a comma to separate answers as needed.) OC. The bird population equals 3000 on July (Type a whole number. Use a comma to separate answers as needed.)
