Sketch a graph of y = x^2, from x = -3 to x = 3. Then sketch a graph of y = 4 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
-.25 units in the x direction and -1.25 units in the y direction.
What are the three basic points
of this graph?
If f(x) = x^2, then what are
- f(x--.25), f(x) +
-1.25, 4 f(x) and 4 f(x--.25) + -1.25?
