Answer:
A
Step-by-step explanation:
We have the graph of the function f(x).
We want to determine which of the given is true of the graph from to .
So, essentially, we are focusing on the last curve (see image below).
First, since the curve is above the x-axis, the curve is positive.
Second, since the curve is curving upwards, this means that it <em>must</em> be increasing. Another way to think about this is to think about the <em>slope</em> of our curve. While we can't calculate the exact slope, the <em>average slope</em> will be positive, so our function is increasing.
So, our answer is A.
And we're done!
