Answer:
Step-by-step explanation:
We can safely focus on 1/x. The smaller x is, the greater 1/x will be. Note that x cannot equal zero. Here we are asked to focus on 1/10 < x < 1, in which 1/10 is obviously the smallest x value. But 1/10 < x < 1 restricts x to numbers greater than 1/10. The graph of y = 10 + 1/x is not defined for x = 1/10, but as we approach x = 1/10 along the graph, we see the graph approaching (but not touching) the maximum value 10 + 1/(1/10), or 20.
