Graphing Quadratic Functions

Complete each of the following steps for the Quadratic Function $f(x)=x^2-4x-2$

Identify the coefficients $a,b$ and $c$ :

$a=,b=,c=-2$

Graph the function on your calculator

Does the graph open up or down and why?:

Write the Vertical Intercept as an Ordered Pair

Plot the Vertical Intercept on the graph using the point tool

Draw the function neatly on the graph using the poly tool by plotting the highest $($or lowest$)$ point and one other point. Then use the point tool $($the dot$)$ to place a dot on the vertical intercept.

$f(x)=x^2-4x-2$
