Answer:
All real values of x where x < −1.
Step-by-step explanation:
There is a turning point at x= 1 and f(x) = -4 and it open upwards.
So it decreases for all real values of x where x < 1. But it passes through the point (-1, 0) after which the values of the function become negative.
So the answer is all real values where x < -1.
The total area of a circle is pi * radius^2
The total area of the circle is pi x 5^2 = 25pi sq. cm.
2/5 of this is success, so the answer is 2/5 * 25pi = 10 pi sq. cm.
