How do you determine a function on a graph?
How do you find the function of X?
- y can be written in terms of x (e.g. y = 3x ).
- If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x”s by 4″s .

What type of graphs are functions?
How do you identify a function?
What is a function in graphing?
Graphs of functions are graphs of equations that have been solved for y! The graph of f(x) in this example is the graph of y = x2 – 3. It is easy to generate points on the graph. Choose a value for the first coordinate, then evaluate f at that number to find the second coordinate.
