Week 11 in pre-calc 11

Posted on by

This week in pre-calc we learned a new way to graph quadratics and linear equations using one and two variables. If it only has 1 variable that means you can only graph along the x-axis. If it has 2 variables you can use both x and y. To start you must first faxtor the equation, then you have to graph it. Once you’ve graphed it you have to decide whether it has a dotted or solid line. If its solid that means < or equal to and > or equal to. If it has a dotted line it mean < or >. Next you have to shade the proper side by choosing a test point. The best point to choose is (0,0).

This is an example of a 2 variable equation graphed.

 

Week 10 in Pre – Calc 11

This week in pre- calc was mainly just review for our mid-term. We didn’t learn any new skills but we spent the week strengthening old ones. We did a lot of practice worksheets to help us memorize what we did. When it came to taking the midterm, I feel I did well on the stuff we did earlier on in the year, but I definetely steuggled when it came to graphing quadratics.
