Use the graph of the curve y = f(x)to solve the inequality f(x) \(\leq\) 0

-1 \(\geq\) x \(\geq\) 1, x \(\geq\) 2

x \(\leq\) -1, 1 \(\geq\) x \(\geq\) 2

x \(\geq\) -1, 1 \(\geq\) x \(\geq\) 2

x \(\geq\) 2, -1 \(\geq\) x \(\geq\) 1

-1 \(\geq\) x \(\geq\) 1, 1 < x \(\geq\) 2

Combining solutions

= x \(\leq\) 1; 1 \(\geq\) x \(\geq\) 2
