Using a graphing tool, we can see that the whole range of the function
is <span>y</span><span> ∈ [0,∞)
Now, in the interval
</span>
{x | –8 < x < 8}.
The range is
y<span>
∈ [0 ; 6.708) </span>
Answer:
The roots of the given equation is x=4,3i,-3i
Step-by-step explanation:
The given cubic equation is

To find the roots we have to equate the equation to zero
ie, 
It can be done by using Synthetic division method
Therfore [tex](x-1) is not a factor or root
now put x=-1
Therfore [tex](x-1) is not a factor or root
similarly let x=2,-2,3,-3 all not equal to zero so the are not roots.
let x-4 is a factor of given equation
then it satifies the equation ie (x-4) is a root
And it may be written as
[tex](x-4)(x^2+9)
Answer:
108.7 ft
Step-by-step explanation:
Put 30 where x is and do the arithmetic.
y = -3.29·30 -10 = -98.7 -10 = -108.7
The trend line predicts the depth to be 108.7 ft after 30 minutes.

<em>Comment on this problem</em>
Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
Assuming the railroad network is properly constructed it would allow for the rapid transportation of large quantities of materials and troops all throughout the nation.
In the event of damage, having enough routes allows rail traffic to be rerouted around damaged rail lines. The ability to get to a location via different routes makes it harder for an enemy to cripple the rail network.
If there is only one line and it gets destroyed, all of the traffic comes to a halt.
