HSF.BF.B.4

Standard

Find inverse functions.

Sub-standards

• HSF.BF.B.4.a — Solve an equation of the form f(x) = c for a simple function f that has an inverse and write an expression for the inverse. For example, f(x) = 2 x³ or f(x) = (x+1)/(x-1) for x ≠ 1.
• HSF.BF.B.4.b — (+) Verify by composition that one function is the inverse of another.
• HSF.BF.B.4.c — (+) Read values of an inverse function from a graph or a table, given that the function has an inverse.
• HSF.BF.B.4.d — (+) Produce an invertible function from a non-invertible function by restricting the domain.
