Standard form of a quadratic equation: Yesterday when we graphed quadratic equations we used the same x values in our tables because the equations we graphed did not have any “b” values. If you were to graph y = x2 + 6x + 8 and used the same x values as we did yesterday, what kind of shape would the graph make? y = x2 + 6x + 8
