Activity 8.1
a. Not every point on the circle has an image point or output because when y=0 or the circle crosses the x-axis, the equation 1/y is undefined.
b. When y= the functional value is equal to the original value of y. This is because 1/1=1 and the sign will the same because of the rules of positive and negative signs in division or multiplication.
c. As y approaches 2, the point is closer to the x-axis because the division is getting closer to 0 so the new y value is getting smaller. As y approaches 0, the point is getting bigger and is farther between.
d. See P_1 and P_1'
