Giving 50pts for these!!
1. Use the quadratic formula to solve x^2+7x+3. Show all of your work. Then describe the solution.

2. Graph the function f(x)=x^2-2x-8 on the coordinate plane.
(a) What are the x-intercepts?
(b) What is the y-intercept?
(c) What is the maximum or minimum value?

3. 4. At what point(s) do these graphs intersect?

Seth’s solution:

The graphs intersect at (-2, 0) and (3,0)
Is Seth’s solution correct? Explain.
