This week, we continued with our unit on rational expressions and learned how to add and subtract rational expressions. Review: Finding the LCD What you do to the bottom of a fraction, you have to do to the top as well Only adding and subtracting the numerators Steps: Factor the denominators if possible Determine the…

This week we learned about rational expressions and learned how to multiply and divide them.  Rational number: a quotient of two integers Rational expression: quotient of two polynomials does not have an equal sign simplifying to it’s the simplest form Rational Equation: an equation that contains at least one fraction whose numerator and denominator are polynomials…

This week we learned how to solve absolute value equations, and then we learned about linear and quadratic reciprocal functions. You can find that there are some patterns that exist when trying to graph reciprocal functions. reciprocal: one pair of numbers whose product is 1 when multiplied together a positive(+) number reciprocates into a positive number a negative(-)…

This week we started our new unit on absolute value and reciprocal functions. We extended our understanding of absolute value functions, and how they would look on a graph as a linear function and a quadratic function. An absolute value is a distance between a number to zero, therefore the absolute value of a negative…

This week in pre-calculus 11, we learned how to solve quadratic inequalities and graph them. This was a review from last year’s math. y=mx+b is the equation used for linear graphs, which are graphs with straight lines that increase or decrease by the same number each time. b is the y-intercept, and m represents the slope…

This week we learned how to graph quadratic equations, which is an expansion of what we have learned so far. The general form of the equation of a quadratic function:  Vocabulary Parabola: the curve of every quadratic function on the graph Vertex: the highest or lowest point of the parabola Minimum point: the lowest point(vertex)…

This week of math we learned about discrinants and In the quadratic equation, the discriminant tells us the number of real solutions. We can find the discriminant by plugging in the correct numbers of the quadratic equation into the radicand of the quadratic formula. quadratic formula: radicand of the formula:  – 4ac discriminant is a…
