Compacted Mathematics Grade 8 (with Integrated Math I): Functions: Building Functions (F-BF)

Build a function that models a relationship between two quantities

F-BF.1

Write a function that describes a relationship between two quantities.

F-BF.1.a

Mostly covered
Determine an explicit expression or steps for calculation from a context.

F-BF.1.b

Fully covered
Combine standard function types using arithmetic operations. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model.

F-BF.1.c

Mostly covered
Compose functions. For example, if T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.

F-BF.2

Fully covered
Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.
