A quadratic equation?
Standard form: ax^2+bx+c where a is vertical shift/stretch and c is the y-intercept
Intercept form: a(x-p)(x-q) where p and q are the roots of the equation and a is the vertical shift/stretch
Vertex form: a(x-h)^2+k where a is the vertical shift/stretch and h is the x value of the vertex and k is the y value of the vertex
h is also the horizontal sift and k is the vertical shift
