Answer 2

To evaluate the function f(x) = 3 + 5x - 3x^2 at the given values of x (-2, 0, 3, 5), we substitute the respective values into the function and perform the calculations.

For x = -2: f(-2) = 3 + 5(-2) - 3(-2)^2 = 3 - 10 - 3(4) = 3 - 10 - 12 = -7 - 12 = -19

For x = 0: f(0) = 3 + 5(0) - 3(0)^2 = 3 + 0 - 3(0) = 3 + 0 - 0 = 3

For x = 3: f(3) = 3 + 5(3) - 3(3)^2 = 3 + 15 - 3(9) = 3 + 15 - 27 = 18 - 27 = -9

For x = 5: f(5) = 3 + 5(5) - 3(5)^2 = 3 + 25 - 3(25) = 3 + 25 - 75 = 28 - 75 = -47

Therefore, when x = -2, the value of f(x) is -19. When x = 0, the value of f(x) is 3. When x = 3, the value of f(x) is -9. When x = 5, the value of f(x) is -47.
