f) I can add and subtract rational expressions with unlike denominators.
9. Explore and analyze graphs of nonlinear equations.
a) I can graph a quadratic equation from vertex form.
b) I can complete the square in a quadratic expression to reveal the max or min.
c) I can graph square root, cube root, and piecewise-defined functions, including step functions and
absolute value functions.
d) I can investigate transformations of linear, exponential, quadratic, and absolute value
e) functions (e.g. horizontal/vertical shifts and the width of the graph).
f) I can solve a simple system consisting of a linear equation and a quadratic equation in two variables
algebraically and graphically.
g) I can interpret and rewrite expressions involving radicals and rational exponents using the properties
of exponents.
h) I can define and explain basic properties of rational numbers (e.g. why the sum or product of two
rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and
that the product of a nonzero rational number and an irrational number is irrational).
10. Compare various methods of data recording to make inferences, predictions, and
to estimate probabilities.
a) I can interpret data from line, bar, and circle graphs, histograms, scatterplots, box-and-
whisker plots, stem-and-leaf plots, and frequency tables to draw inferences and make predictions.
b) I can represent data using dot plots, histograms, and box plots.
c) I can represent data on a scatterplot and interpret the line of best fit.
d) I can identify the most efficient way to display data.
e) I can identify the effect on mean, median, mode, and range when a set of data is changed.
f) I can analyze and interpret the shape of the data distribution to compare the center (median, mean)
and spread (interquartile range, standard deviation) of two or more different data sets.
g) I can summarize, represent, and interpret data on two categorical variables.
h) I can find the probability of a simple event and compound events.
i) I can distinguish between dependent and independent events.
