Question 13

>

Finding Horizontal Intercepts of Quadratic Functions. Graphing/Intersection Method

f(x) = − x² + 4x – 4

1) Write the Vertical Intercept as an Ordered Pair

2) Write the Vertex as an Ordered Pair

3) Draw the function neatly on the graph using the

poly tool by plotting the vertex and vertical intercept.

4) Use your graphing calculator to determine the

horizontal intercept(s) of ƒ(x) = −x² + 4x − ² 4.

Write your answers as ordered pairs separated by

commas. If none exist, write DNE.
