Function Notation & Inverse Functions T/F: If f(x)=2x+3, then f−1(4)=11.

In a survey of a TriDelta chapter with 50 members, 16 were taking mathematics, 34 were taking English, and 5 were taking both. How many were not taking either of these subjects? ​ __________ members

Function Notation & Inverse Functions T/F: If f(3)=7, then f−1(7)=3.

Perform the given operations. Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} (U represents the universal set). ​  

Piecewise Functions T/F: To evaluate a piecewise function at x=4, you first determine which rule includes x=4.

Irrational (Radical) Equations T/F: To solve an equation containing a square root, you can isolate the radical and then square both sides.

Irrational (Radical) Equations T/F: The equation

Solve using Cramer’s Rule:

Polynomial Functions & Equations T/F: If f(3)=0, then x=3 is a zero of the polynomial.
