Question

Which graph has the following characteristics?

Answer 1

Answer:

The graph (3) matches the criteria.

Step-by-step explanation:

See the graph attached.

Here we have to identify the graph with characteristics  

(i) Three real zeros.

(ii) As $x \to -\infty, f(x) \to -\infty$ and  

(iii) As $x \to \infty, f(x) \to \infty$

Now, the graph (3) matches the criteria.

There are three real zeros and the right arrow and the left arrow suggests that as $x \to -\infty, f(x) \to -\infty$ and as $x \to \infty, f(x) \to \infty$. (Answer)
