CPM Homework Help : INT3 Problem 3-16

For each of the functions in problem 3-15, sketch the graph of $y=f(-x)$ .

Hint:

Think about a blank graph. Where are all of the points with a positive $x$ -value?
Where are all of the points with a negative $x$ -value? How are these points related?

Answer (a):

Downward parabola, vertex at (4, comma 2), with points at (3, comma 0), & (5, comma 0).

Answer (b):

Decreasing rational function, asymptotes: x axis &, x, = 2, left section, opens down, is below x axis & left of, x, = 2, & passes through the point (1, comma negative 1). Right section, opens up, is above, x axis, & right of, x, = 2, & passes through the point (3, comma 1).
