#### Answer

(a) $f(1)=3$ (b) $f(-1)\approx-0.4$ (c) $x=0$ and $x=3$ (d) $x\approx-0.6$ (e) Domain: [-2,4] and Range: [-1,3] (f) Domain: [-2,1]

#### Work Step by Step

When the question says estimate, the answers does not need to be exact, but it has to be in a range. The estimated answer of 3(b) has to range from -0.2 to -0.4, and the estimation of 3(d) has to range from -0.4 to -0.6. On other questions, you have to state the exact values by looking at the graph.
