a.a< –1

b . –1 <a< 0

c . 0 <a< 1

d . 1 <a

The figure shows the graphs of*f(x)*=*x*3 and*g(x)*=*ax*3. What can

a.*a*< –1

b . –1 <*a*< 0

c . 0 <*a*< 1

d . 1 <*a*

2)

3)

Let us examine #2:

We know that

Thus,

Since

Thus, .

Let us examine #3:

We know that

This leads to, but we already know that, so we did not gain anything.

But if we look at we see that for .

Thus,

Since it tells us that .

Thus,
