• Function

• Not a Function

This graph represents which function?

• y = -2x

• y = 2x

• y = -2x + 1

• y = 2x - 1

Is the relation a function?

• yes, it is a function

• no, it is not a function

• not enough information to determine

• The graph of f(x) always exceeds the graph of g(x) over the interval [0,5].

• The graph of g(x) always exceeds the graph of f(x) over the interval [0,5].

• The graph of g(x) exceeds the graph of f(x) over the interval [0,4], the graphs intersect at a point between 4 and 5, and then the graph of f(x) exceeds the graph of g(x).

• The graph of f(x) exceeds the graph of g(x) over the interval [0,4], the graphs intersect at a point between 4 and 5, and then the graph of g(x) exceeds the graph of f(x).
