I'm struggling with graphs. Any help appreciated. Thanks
The figure shows the graphs off(x) = x3 and g(x) = ax3. What can
you conclude about the value of a?
a. a < –1
b . –1 < a < 0
c . 0 < a < 1
d . 1 < a

We see the following:
1)
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,
.
