Question 11

<

Finding Horizontal Intercepts of Quadratic Functions. Graphing/Intersection Method

f(x)

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 f(x)

x² - 4x + 4. Write

your answers as ordered pairs separated by commas. If

none exist, write DNE.
