Exercise 15 Page 423

Push Y= and type the function in the first row.

Graph:

It is a vertical shrink by a factor of 1100 of the graph of y=- 4x^2.

Practice makes perfect

Let's enter the function in the calculator by pushing Y= and typing it in the first row.

Window with inequality

Next, by pushing GRAPH, the calculator will draw the graph of the equation.

Window with a graph

We see that the graph of y=- 0.4x^2 is a vertical shrink by a factor of 1100 of the graph of y=- 4x^2.
