Answer:
The values of n are less than 3 and more than (-5/2)
Step-by-step explanation:
The given inequality is :
-5 < 2n <6
We need to write the values of n.
Dividing both sides of the inequality by 2. So,

So, the values of n are less than 3 and more than (-5/2).
Using PEMDAS, You know that you have to multiply first so 3*2 is 6. Than you have to add 6+4 which gives you 10... So there for 10 is your answer....
f(x) = sqrt(x)
f(17) = sqrt(17)
it is close to sqrt(16)=4
so to the nearest integer
f(17) = 4
