Question

For what values of x is the graph of y = $\frac{2}{5 - x}$ concave upward?

x < 5
x > -5
x > 5
No values of x

Answer 1

Answer: y = 2 / (5 - x)

There is an asymptote at x = 5 and for x values less than 5,  values of  y are negative and approach negative infinity.

For values x > 5, y values come down the graph from positive infinity  and  they  stay positive and  tend to 0 as  x approaches  positive infinity.

So the graph is concave upward for x  values  greater than 5.
