What do I look for when asked to find the solution/root/zero to a quadratic?

Back

I look for where the parabola crosses the x axis

What do I put in Desmos for:

"which FUNCTION best represents the graph"

or

"which EQUATION best represents the RELATIONSHIP"

(LINEAR)

Back

use y1~mx1+b to find the equation of the line

Name four things you know about this line:

Back

1. Undefined slope

2. x = 2

3. Parallel to the y-axis

4. Perpendicular to the x-axis

How do you solve a function for a given x in Desmos?

Back

f(x) = equation

Substitute the number for x in f(x)
