Question 909255: write an equation for a quadratic given the following:
x-intercepts are (2,0) and (5,0) and y-intercept is (0,6)
I know that it means I have (x-2) and (x-5) for my equation. I multiplied them to get x^2 - 7x + 35. I'm not sure how to incorporate the y-intercept.
Do I put the equation equal to 6 and solve?
6= x^2 - 7x + 35
Is my answer x^2 - 7x -29?
