Question

How do you graph `y<x^2-5x+4`?

Answer 1

See below.

Explanation:

First graph `y=x^2-5x+4`. Use a dashed line since this is a less than and not a less than or equal to inequality and the curve will not be an included region.

With graph plotted test for values inside and outside of the parabola.

Inside parabola:

`(2,2)`

`2 < (2)^2-5(2)+4`

`2 < 4-10+4`

`2 < -2`

This is false, so included area is outside of parabola.
