Week 14 in Precalc 11

This week in math we learned how to multiply and divide rational expressions. A rational expression is a quotient of two polynomials, so it’ll look like a fraction but with

Week 13 in Precalc 11

This week in math we learned how to graph linear reciprocal functions. The parent function would be in the format: f(x)=mx+b, but the reciprocal of that would look like f=.

Week 12 in Precalc 11

This week in math we learned how to solve systems algebraically when one is a linear system and the other quadratic using substitution. We learned about this method in Math

Week 11 in Precalc 11

This week in math we learned how to graph quadratic inequalities in two variables. Some basic information to know first is what the signs mean, e.g. < or > means

Week 10 in Precalc 11

This week in math we learned how to solve quadratic inequalities using a sign chart. To recall, in previous years we had learned how to solve linear inequalities and how

Week 9 in Precalc 11

This week in math we learned how to convert quadratic functions into general form, factored form, and standard form from other forms. General form is y=a+bx+c, where c is the

Week 8 in Precalc 11

This week in math we learned how to determine the properties of a quadratic function. On a graph, a quadratic function looks like a U or upside down U, it’s

Week 7 in Precalc 11

This week in math we learned about discriminants and how to determine the nature of a root. The discriminant equation is -4ac, as taken from the part of the quadratic

Week 6 in Precalc 11

This week in math we learned how to solve quadratic equations using the zero product law. A quadratic equation is one that has two answers. A linear equation has one

Week 5 in Precalc 11

This week in math we learned how to factor polynomial expressions, specifically ‘ugly’ ones using the ‘box method’. A helpful phrase to figure out if a polynomial expression is ugly
