A 10-3AStd9b: I can determine if a representation is a function and state its domain and range.
Define function:
Is the graph a function?
Why? Use the vertical line test.
Is the graph a function?
Why? Use the vertical line test.
If f ( x )=√2 x+1 then calculate f (4 )
If f ( x )=√2 x+1 then solve f ( x )=7
