Graphing: This year in precalculus, we have mainly been looking at quadratic function graphs and how the different forms give different information to graph the most accurate parabola. General form: y-intercept slope Factored form:  () () x-intercepts axis of symmetry Completing the square (standard): +q vertex Absolute value function:  Before I had an idea of what an…

This week in pre calculus 11, we studied our last unit on trigonomitry, which was an add on to what we’ve learned and covered in math 10, but unlike math 10, we learned how to find the angles and sides of a triangle without a 90° angle (right triangle), through sine law and cosine law….

This week in pre-calculus, we learned how to solve rational equations. We can cross multiply when there are two fractions on both sides of the equal sign, but when there are more than two fractions, you would have to find the common denominator and multiply each side to get rid of the denominator to solve the equation….

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…
