This week was a very short week so we didn’t go over too much stuff but we still learned a couple of things. We learned how to graph quadratic and linear inequalities, to graph a quadratic inequality you would need to find the y-intercept and the vertex and use those numbers to graph it and find the solutions and where it’s going to be shaded in the graph. So, for example, . The y-intercept would be 8 and you can tell it opens up since the is positive, and the pattern is 1, 3, 5 because the leading coefficient is 1. So now you would factor into , and from that, you can find the vertex which would be -4 and -2 which would be your x-intercepts. To find the vertex you would and you vertex would be -3 and by plugging it into your equation you could find the minimum point connected to the vertex and graph it.

This week in math we started a new unit and it was an intro to Absolute value functions, this really changed things up and made graphs look crazy on desmos. When I say it looked crazy on demos it really does because when you have an equation like on a graph as shown right here […]
