Consider the graph of a quadratic function shown to the right. A. Write a quadratic function that has x^2 -coefficient equal to 1 and has the x-intercepts indicated. B. Write a quadratic equation in the variable x, with X^2 -coefficienent equal to 1, that has solutions of -6 and -2 c. How many different quadratic functions can have x intercepts of -6 and -2? D. How many different quadratic equations in one variable can have solutions of -6, and -2?

    The graph is a u shape and crosses on the x-axes at both -2, and -6.

    A. Write a quadratic function that has x^2 - coefficient equal to 1 and has the x-intercepts indicate: y=x^2+bx+c 0 Intercepts are -6 and -4, so: 0=(-6)^2+b(-6)+c 0=(-2)^2+b(-2)+c -36=-6b+c -4=-2b+c
