TRUE OR FALSE? (Work with real numbers throughout.) The singular values of any matrix A are the eigenvalues of matrix AT A.

Week 3 Chapter 1: Functions and Models 1.1 Function – a rule/pattern we determine from data points to predict values where data is missing (each x value has one y value) x→F →F(x) input functionoutput A function can only be a function if it passes the vertical line test (i.e. each x value has no more than one y value) A function is one-to-one if it passes the horizontal line test (i.e. each y value does not have more than one x value) Ex1. Give an equation, domain, and range for this graph: Equation: f(x= {+2,∧x<0 x ,∧x≥0 Domain: (−∞,∞) Range: −∞,−1 )∪¿ Ex2. Sketch a graph and give the domain & range for this equation: f( )=−2− 1√x
