Question

The graph y = -5/(x-2) is concave downward for all values of x such that:

Answer 1

a. x < 0
b. x < 2
c. x < 5
d. x > 0
e. x > 2

Answer 2

@zepdrix Is it b. x < 2?

Answer 3

If I look on the graph, it doesn't really concave down after x value of 2 or so. It kinda just goes straight in a line.

Answer 4

So the graph of 1/x looks like this, yes?
