CPM Homework Help : INT3 Problem 7-49

Sketch a graph for each of the following functions and label the $x$ - and $y$ -intercepts.

$f\left(x\right) = 3\left(x - 4\right)^{2} - 5$
Hint (a):
The equation of this quadratic function is in graphing form. Where is its vertex?

$g\left(x\right) = 2x^{2} - 3x - 5$
Hint (b):
Rewrite this equation in factored form. What are the $x$ -intercepts? (You should be able to tell once the equation is in factored form.)
