What does a in the quadratic vertex formula do? a ( x − h ) 2 + k . In both forms, y is the y -coordinate, x is the x -coordinate, and a is the constant that tells you whether the parabola is facing up ( + a ) or down ( − a ).
WHAT IS A in vertex for? ax2 + bx + c (that is, both a’s have exactly the same value). The sign on “a” tells you whether the quadratic opens up or opens down. Think of it this way: A positive “a” draws a smiley, and a negative “a” draws a frowny.
What is the role of a in a quadratic equation? We need to find the value of x that makes A as large as possible. A is a quadratic function of x, and the graph opens downward, so the highest point on the graph of A is the vertex. Since A is factored, the easiest way to find the vertex is to find the x-intercepts and average.
What is the effect of a of a quadratic equation in vertex form? ax2 + bx + c (that is, both a’s have exactly the same value). The sign on “a” tells you whether the quadratic opens up or opens down. Think of it this way: A positive “a” draws a smiley, and a negative “a” draws a frowny.
