### Algebra 1 PARCC: Where’s the parabola?

Graphing parabolas is expected on the PARCC algebra 1 test (and in many algebra classes). Can you graph a quadratic function?

Graphing the solution to a system of linear inequalities is likely to come up on the PARCC test in algebra 1. Are you ready?

Measures of central tendency and the spread of data, including outliers, will come into play as students take the PARCC test in algebra 1 this spring.

Solving equations for a variable of interest is required in algebra 1 on the PARCC test (and in the Common Core). Students find the radius of a circular pool.

Is a given ordered pair on the graph of a function? Algebra 1 students should be able to figure it out, esp. those who will take the PARCC test this year.

The zeros of a polynomial are the *x* values when the polynomial equals 0. Do you know how to find the zeros?

Modeling real-world situations sometimes requires a linear model, sometimes an exponential model, sometimes a coffee model.

The point at which something more expensive to buy becomes less expensive because operating costs aren’t as high can be modeled with a system of linear equations.

We have lots of equivalent ways of writing equations for lines, or linear functions, including slope-intercept, point-slope, and Ax+By=C.

You can find the average of a set of data and use it to model the behavior of a system that is under investigation in the real world.
