F(x)= if -1 < x < 1
if 3 < x < 5

(x−4)²+(y)²=1

Step-by-step explanation:

If you translate this into English, you get something like this:

The y value lies between -1 and 1, if the x value is between 3 and 5, This could very well be a circle with the center point M and a radius of 1.

The x-coordinate of the middle lies between 5 and 3, which is 4

The y-coordinate of the middle lies between -1 and 1, which is 0.

So the middle is (4 , 0) and radius is 1

The circle equation (xa) 2 + (yb) 2 = r 2

The circle with center M( a b ) and radius r has as a comparison:

(x - a)² + (y - b)² = r²

with a = 4 and b = 0 and r = 1

(x − 4)² + (y - 0)² = 1²

(x−4)²+(y)²=1

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
