This may help you
he functión Cot[x/2] is not continuos in the points
<span>x=2nπ, where n=0,1,2,3,...</span>
You can check it with a calculator. So the function is not continuos in
the domain the problem gives you, so the Rolle's theorem can not be
applied. If the inteverval was,
<span>[π/2,3π/2]</span>
Then we could apply the Rolle's theorem.
D (56.5)
Originally, the train traveled 340 miles in 8 hours
If we use the formula d/t, we'll have 340/8, which is 42.5
If we add 14, then we'll have 56.5, or d
There are no values of x that make the equation true so there is no solutions.
This is the correct answer you worked it out and then diagram u drew is the right thing to do and I hope u do well on ur class
Answer:
Function.
Step-by-step explanation:
A relation is a function every x that in your domain only gets assigned to exactly one number in your range.
Basically if you have a set of points and you see that the same x is being used more than once, then it isn't a function (unless for some reason they repeated the same point).
So the x's I see in the order that your points are is 3,1,-1,-2. All of these x's are different so it is a function.
