Sketch a graph of y = x^2, from x = -3 to x = 3. Then sketch a graph of y = .3333333 x^2 over
the same domain.
- By what factor do we vertically
stretch the first graph to obtain the second?
- What are the three basic points of
the first graph (i.e., the vertex and the points 1 unit to the right and left of the
vertex)?
- What are the three basic points of
the second graph?
Sketch the second graph shifted
-1.75 units in the x direction and .25 units in the y direction.
What are the three basic points
of this graph?
If f(x) = x^2, then what are
- f(x--1.75), f(x) +
.25, .3333333 f(x) and .3333333 f(x--1.75) + .25?
