10-11.

Graph each of the following functions and label the $x$ - and $y$ -intercepts.

$f(x)=3(x-4)^2-5$
Hint 1(a):
The vertex of this parabola is at $(4, -5)$ .
Make a table to accurately sketch the graph.
Hint 2(a):
To find the $x$ -intercepts, solve the equation
$0 = 3(x - 4)^2 - 5$ .
Your solutions should match your graph.
Hint 3(a):
To find the $y$ -intercept, solve the equation
$y = 3(0 - 4)^2 - 5$ .
Your solution should match your graph.

$g(x) = 2x^2 - 3x - 5$
Hint (b):
$\text{The }x\text{-coordinate of the vertex of this parabola}$ $\text{is at }x=-\frac{b}{2a}.$
