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

A

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

B

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

C

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

D

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

correct option: b

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

Combining solutions

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