Y ax - 22 -3 6 a5 - 22 -3 6 9a - 3. For example we have the formula y 3x 2 - 12x 95. Simplify each equation then use the method of your choice to solve the system of equations for a b and c.
The variables h and k are the coordinates of the parabolas vertex.
Y x 2 - 3x 13. A quadratic equation can be solved by using the quadratic formula. This method also works if you are given a graph and the ve. The highest degree the greatest exponent of the function is 2.
