The solution of a +b > 12 is a > -3. what is the value of b?

Which function is represented by the graph

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.

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5
