CPM Homework Help : CCA2 Problem 1-84

Use any method to find the points of intersection of $f(x)=2x^2−3x+4$ and $g(x)=x^2+5x−3$ .

Hint:

Refer to problems 1-46 and 1-71.

More Help 1:

How do these functions differ from the functions in problems 1-46 and 1-71?

More Help 2:

The $y$ -value of one of the points of intersection of the graphs will be too large to be seen
on most graphs. The graphing window would have to include $y$ -values $0\le y\le90$ .

Answer:

There are two points of intersection: $(1,3)$ and $(7,81)$ .

Use the eTool below to find the points of intersection for the given functions.
