# Function Graphs

Graphs are visual representations of functions. If you know how to read graphs, you can say a lot about a function just by looking at its graph. Learn this fine art of mathematical divining.

# Interpreting Graphs of Functions

In the above graph, if $$f(0) = 7$$, what is the value of $$f( 4)$$?

The above graph consists of 2 straight lines. If $$f( 5) = 20$$, what is the value of $$f( 6 )$$?

The above graph consists of 2 straight lines. If $$f(1 ) = 5$$, what is the value of $$f( 9 )$$?

The above graph represents an algebraic function that is defined on the domain $$[0, 10]$$. If $$f( 2) = 3$$ and $$f(3) = 5$$, how many solutions are there to $$f(x) = 1$$?

In the above graph, if $$f(0) = 3$$, what is the value of $$f(9)$$?
