Answer:

48

Explanation:


y = 0

is basically the horizontal axis.

First, find the integral of x^2-25.

Remember that

integral of a constant is that constant times x.

Also that

to take the integral of a power function, add 1 to the degree and divide by that same degree.


y = {x}^(2) - 25

We then get


\frac{ {x}^(3) }{3} - 25x

Evaluate at -3


\frac{ - 3 {}^(3) }{3} - 25( - 3)


- 27 + 75 = 48

Then we evaluate at 0


\frac{0 {}^(3) }{3} - 25(0) = 0

Next, we subtract the the answer then we get


48 - 0 = 48
