Function: Graph

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?

Re: Function: Graph

Thank you.

When I start evaluating for A-D, do I plug in those numbers? If so, where?
I'm still a bit confused...

[color=#000000]For (a) for example h(3)=5 and h(1)=3 (look at the table for the values) and so h(3)-h(1)=2.[/color]

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

Re: Function: Graph

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.
