Answer:
f(- 3) = 8
Step-by-step explanation:
To evaluate f(- 3), substitute x = - 3 into f(x) , that is
f(- 3) = 2(- 3)² - 10 = 2(9) - 10 = 18 - 10 = 8
4 is the whole number equivalent to 8/2.
First compute the area of the rectangle:

We have to find the radius of the circle:
circonférence of circle given radius is:

We get the equation:

Solving the above equation for r we get:

Compute the area of the circle like this:

The white area is the difference of the area of the rectangle and the area of the circle:
