Answer

a) $f(6)=8$ b) $x=-6$ c) $\text{Domain: all real numbers} \\\text{Range: all real numbers} $

Work Step by Step

a) Based on the graph, when $x=6,$ the value of $y$ or $f(x)$ is $8.$ Hence, $ f(6)=8 .$ b) Based on the graph, when $y$ or $f(x)$ is $0,$ the value of $x$ is $ x=-6 .$ c) Based on the graph, the values of $x$ and $y$ can be any real number. Hence, \begin{array}{l}\require{cancel} \text{Domain: all real numbers} \\\text{Range: all real numbers} .\end{array}
