Outcomes

A1.N.Q.A.1

Use units as a way to understand real-world problems.*

A1.N.Q.A.1.B

Use appropriate quantities in formulas, converting units as necessary.*

A1.F.IF.A.1

Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

A1.F.IF.A.2

Use function notation.*

A1.F.IF.A.2.A

Use function notation to evaluate functions for inputs in their domains, including functions of two variables.

A1.F.IF.A.2.B

Interpret statements that use function notation in terms of a context.

A1.F.IF.A.3

Understand geometric formulas as functions.*

A1.MP1

Make sense of problems and persevere in solving them.

A1.MP3

Construct viable arguments and critique the reasoning of others.

A1.MP4

Model with mathematics.

A1.MP6

Attend to precision.

A1.MP8

Look for and express regularity in repeated reasoning.
