Watch this video to learn how to graph a quadratic function of the form ax2 +bx + c, where a, b, and c are constants (and a?0). All functions of this form describe the graph of a parabola (u-shape) that either opens upward or downward. To graph a quadratic function: Consider the leading coefficient (the value of a) to determine if the parabola opens upward (postive a) or downward (negative a) Calculate the vertex of the parabola from a and b. The vertex is the highest or lowest point of the parabola. Find the x-intercept(s) (zeros) Find the y-intercept. (Found by plugging x=0 into the function).
Graphing Quadratic Functions - Example 1 is a free educational video by PatrickJMT.It helps students in grades HS practice the following standards HSF.LE.A.3.
1. HSF.LE.A.3 : Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function..
