# How do you graph #F(x)=x^2-6x+8#?

##### 1 Answer

See answer below

#### Explanation:

Given:

This function is a quadratic - a graph of a parabola.

Factor and let **find the x-intercepts** :

#x - 2 = 0 " "=> x = 2; " "x - 4 = 0 " "=> x = 4

**Find the y-intercept** let

**Find the vertex** . When the equation is in

the vertex is

vertex:

Plot a couple of other points using point-plotting. Since

graph{x^2 -6x + 8 [-5, 10, -2, 10]}
