**need an answer checked - algebra**

Given a quadratic equation y = ax^2 + bx + c, (i) What is the effect of changing the value of the number c on the parabola? In other word, if two parabolas have the same coefficients a, and b, but different values for c, how will their graphs differ? My answer: If you have ...
