Move the slider to change the value of A.
Observe how the graph changes as the value of A changes.
Activity 1
Observation 1
Describe the change in the graph of y = (Ax)2 + 1 when the value of A increases from 1 to 4.
Observation 2
Sketch the graph after this transformation.
Observation 3
Let (1, 2) be a point on the curve y = x2 + 1. Observe and write down the new coordinates of this point after going through this transformation.
Label this point on the transformed graph that you have drawn in Observation 2.
Observation 4
Which value is changed?
Observation 5
What is the replacement of variable involved in transforming the graph of y = x2 + 1 to y =(4x)2 + 1?
Replace x by ______________
