Graphing an Eliipse and Interval Notation
Complete the square and sketch a graph of the following ellipse. Give the coordinates of the centre and the four vertices. What is the length of the major axis?
4x^2 + y^2- 8x + 4y -8 = 0
Solve and graph your solutions on the number line and express your answers in interval notation.
1. |3x – 7| >= 23
2. 1/2 |5-2x| < 7
