Students apply their knowledge of quadratic functions to create and analyze a regression equation of a data set.
Log in to see state-specific standards (only available in the US).
Fit a function to the data; use functions fitted to data to solve problems in the context of the data.
Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
Graph linear and quadratic functions and show intercepts, maxima, and minima.
Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.
Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function 𝘩(𝘯) gives the number of person-hours it takes to assemble 𝘯 engines in a factory, then the positive integers would be an appropriate domain for the function.
