  1. 2.7 Objective; _____To graph and write absolute value functions_

  2. Check point; In the graph y=|x+4|-8, name the vertex. _____ (-4, -8)________ Plot another point on the graph. ___(0, -4)_ Use symmetry to find a third point _(-8, -4)_ and sketch the graph.

  3. Check point; Tell what you know about the graph before plotting any points. y= -3|x-1| +2 Vertex; __(1,2)_ opens; _ down__ stretch or shrunk stretch by a factor of 3 point ___(0,-1)__ for all functions y= a∙f(x-h)+k stretch (if a>1) or shrink(if a<1) Vertex (h,k) also turn up (if a is positive) or down (if a is negative)

  4. Write the equation of the shown graph. • 1. 2. • (1,4) • (1,2) (0,2) • (-1,0) • y = a |x – h| + k y = a |x – h| + k • y = a |x – 1| + 2 y = a |x – 0| + 2 • 0 = a |-1 – 1| + 2 4 = a |1 – 0| + 2 • 0 = a | – 2| + 2 4 = a |1 | + 2 • 0 = 2a + 2 4 = a + 2 • -2 = 2a 2 = a • -1 = a • y = -1 |x – 1| + 2 y = 2 |x | + 2
