Solve using Cramer’s Rule:

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

“All sparrows are birds”. Rephrase this using set terminology. ​  

Matrix Algebra T/F: If A has an inverse, then AA−1 = I.

Let U = {1, 2, 3, 4, 5, 6, 7}, A = {1, 2, 3, 5} and C = {1, 4, 7}. List all the members of the following set.​

Piecewise Functions T/F: A piecewise function must have a break or discontinuity in its graph.

Exponential Functions & Equations T/F: The function f(x)=x2 represents exponential growth.

Domain & Range T/F: The range of a function is the set of all possible y-values or outputs.

Polynomial Functions & Equations T/F: If a zero has even multiplicity, the graph typically touches the x-axis and turns around at that zero.

Exponential Functions & Equations T/F: If 2x=25, then x=5.
