Answer:
Increasing in the interval
Step-by-step explanation:
We have been given a function:
![f(x)=x^2+5x+6](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B5x%2B6)
Please look at the attachment to see the increasing interval of the graph
We can see that the graph is increasing in the interval
The options given in the question are not correct because graph is not increasing in any of these intervals.
Answer:
<h2>C. y ≥ 9x − 6.5</h2>
Step-by-step explanation:
![-18x+2y\geq-13\qquad\text{add}\ 18x\ \text{to both sides}\\\\-18x+18x+2y\geq18x-13\\\\2y\geq18x-13\qquad\text{divide both sides by 2}\\\\\dfrac{2y}{2}\geq\dfrac{18x}{2}-\dfrac{13}{2}\\\\\boxed{y\geq9x-6.5}](https://tex.z-dn.net/?f=-18x%2B2y%5Cgeq-13%5Cqquad%5Ctext%7Badd%7D%5C%2018x%5C%20%5Ctext%7Bto%20both%20sides%7D%5C%5C%5C%5C-18x%2B18x%2B2y%5Cgeq18x-13%5C%5C%5C%5C2y%5Cgeq18x-13%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%202%7D%5C%5C%5C%5C%5Cdfrac%7B2y%7D%7B2%7D%5Cgeq%5Cdfrac%7B18x%7D%7B2%7D-%5Cdfrac%7B13%7D%7B2%7D%5C%5C%5C%5C%5Cboxed%7By%5Cgeq9x-6.5%7D)
