Question

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing? (–6.5, ∞) (–5, ∞) (–∞, –5) (–∞, –6.5)

Answer 1

Answer: the Answer is b

Step-by-step explanation:

Answer 2

Answer:

Increasing in the interval $(-2.5,\infity)$

Step-by-step explanation:

We have been given a function:

$f(x)=x^2+5x+6$

Please look at the attachment to see the increasing interval of the graph

We can see that the graph is increasing in the interval $(-2.5,\infty)$

The options given in the question are not correct because graph is not increasing in any of these intervals.
