Question

The graph below shows the function f(x)= 5x+10/x^2+7x+10

Answer 1

Answer:

C. x = -2

Step-by-step explanation:

A proper graph of the function will have an open circle at (-2, 5/3), so you should be able to read the answer from the graph.

The factorization is ...

... f(x) = 5(x +2)/((x +5)(x +2))

The removable discontinuity is created by the factor (x+2)/(x+2), which is undefined at x = -2.
