Question

7. **Write the equation of the graph shown below. 6 4 -2 2

Answer 1

The graph represents an absolute value function. f(x) = lxl

f(x) = 3 lxl-3

The vertex of an absolute value function is: (0,-3) , so we have to add a minus 3 to the equation.

By multiplying lxl by 3 we narrow the graph.
