1-84.

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

Refer to problems 1-47 and 1-71.

How do these functions differ from the functions from problem 1-47 and problem 1-71?

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 $0 ≤ y ≤ 90$.

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

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