Answer

Answer:

(a) No (b) $(-4, - 2)\cup(0,3)$ (c) $-4,3$

Explanation:

Step1: Check $f(5)$

Locate $x = 5$ on graph. $y=f(5)<0$.

Step2: Find $x$ for $f(x)>0$

Identify $x$-intervals where graph is above $x$-axis.

Step3: Find $x$ for $f(x)=0$

Locate $x$-values where graph intersects $x$-axis.
