Question #4180f Algebra Quadratic Equations and Functions Quadratic Functions and Their Graphs 1 Answer reudhreghs Feb 28, 2017 cc is the yy-intercept. Explanation: At any value of aa, if x=0x=0 then ax^2=0ax2=0. This means that at the point x=0x=0 (which is on the yy-axis), the yy value will always just be cc. This is called the yy-intercept - the point at which the curve crosses the yy-axis. If cc changes, then the graph will move up or down.
