Presentation Transcript

1. Adding and Subtracting Rational Expressions

2. WARM UP Suppose y varies inversely with x. Write an equation that includes the point (4,2) 1) The length of a violin string varies inversely as the frequency of its vibrations. A violin string 14 in long vibrates at a frequency of 450 cycles per second. Find the frequency of a 12- in violin string. 2)

3. Review Identify vertical and horizontal asymptotes and state domain and range 3 y= x-2+1 1)

4. Review of Multiplying Multiply the following: 1. 2. 2. .
