Hi every one mine name is Angela lynch

First you have to find the derivative of g(x). Then set that equal to 0 and solve for the value(s) of x. Then plug your critical #'s into the original equation. The largest # will be your relative max and the smallest # will be the relative min.

Another way to write 44n would be 44 x n because you are multiplying 44 by n, not dividing them.

I'm pretty sure it would have traveled 18.5 miles. Try drawing it out on a graph (7.5 down, 3.5 right, etc.). Then add up all the distances it traveled right up to where it reaches a position where it already went. Hope this makes sense.

Thank you so much ! :D
