Evaluating functions from graphs

• To evaluate a function from a graph, we want to put our pencil or mouse on the x value we are given.

• Next, we go up or down until we are touching the line or curve, and identify the y-value there.

Is the table linear?

• To determine if a table is linear, we subtract the consecutive outputs. If we get the same number each time the table is linear.

is the table exponential?

• if we divide the consecutive entries and get the same number each time, the table represents an exponential function.

is the table quadratic?

• For now, if it is not exponential or linear it is quadratic.
