Find a formula for the piecewise function graphed in the figure. You may assume that the graph continues to the left without end. (a) The formula for the left piece of $f(x)$ is $f(x) =$  help (formulas) for all $x$ that satisfy the inequality $x <$  help (numbers) (b) The formula for the right piece of $f(x)$ is $f(x) =$  help (formulas) for all $x$ that satisfy the inequality  help (inequalities)
