Determining the zeros of a quadratic equation
In this Unit we will cover:
Guten tag everyone I'm sorry that we ran out of time last class but I'll explain what we didn't cover last class now
This here is a quadratic equation shown in graph form. We'll be working With this specific graph today.
Like in the last wideo let's idenitify the x and y-intercpts. Remember, the x-intercpt is where the line meets the x-axis while the y-intercept is where the line crosses the y-axis. You might encounter a question like this on a test so pause the video if you want.
Did you figure it out?
The y-intercept is at (0,-10)
The x-intercets are at both (-5,0) and (2,0)
If you got something else... then please try again
This is an example of a function
You may just have an equation with no graph at all!
