Answer
a) $\left[\frac{5}{3},3\right]$.
b) $\left[\frac{8}{3},\infty\right)$.
Work Step by Step
Part a.
From the graph, the values of $x$ that satisfy the inequality $-1\leq y\leq3$ are $\left[\frac{5}{3},3\right]$.
Part b.
From the graph, the values of $x$ that satisfy the inequality $y\leq0$ are $\left[\frac{8}{3},\infty\right)$.
