Which function is shown in the graph below?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
