Step-by-step explanation:

The function is positive when it is above the x-axis

The following x values are where the function has positive y coordinates:

(-2,0)

The function is negative when it is below the x-axis

The following x values are where the function has negative y coordinates:

Mashcka [7]

Answer:

No, incorrect

Step-by-step explanation:

Given

Q(s) = -4s^3 + 7s^2 - 24;
s = -4 and 1

Verifying zeroes

Q(-4) =

-4(-4)^3 + 7(-4)^2 - 24 =
256 + 112 - 24 =
344
Incorrect as 344 ≠ 0

Q(1) =

-4(1)^3 + 7(1)^2 - 24 =
-12 + 7 - 24 =
-29
Incorrect as -29 ≠ 0
