When solving a graph, does it contain the same method as regular functions? Like for example, finding the input and output? I believe there are four different ways to solving functions. • Verbally (in words) • Algebraically (by formula) • Visually (by a graph) • Numerically (by tables of values) < I have trouble with understanding that concept. Although, when it comes to graphs, does that rule still apply? How would I begin solving this graph?

Thank you. When I start evaluating for AD, do I plug in those numbers? If so, where? I'm still a bit confused...

For what it's worth, the graph matches that of h(x) = (x + 2)(x  2)².

Alright, I solved and my answers are: (a) Evaluate h(3)?h(1)= (b) Evaluate h(2)?h(?1)= (c) Evaluate 3h(?2)= d) Evaluate h(2)+6=

You should have omitted use of h after each "=" symbol. (a) h(3) ? h(1) = 5  3 = 2, etc.
