I said the one with the fraction

so was the right answer for the end behavior as x -> -3 f(x) approaches negative infinity and as x -> positive infinity f(x) approaches positive infinity?

What was the answer for the short answer the was like cube root of x multiplied by square root of x

What the compounding one again? @kimclan1

p sure the compounding one was initialamount(1.000025)^12

The answer was x^(5/6). It said to express it with a rational exponent so you could not say the 6th root of x to the 5th. You could probably however get away with x^(10/12) because it technically is equivalent and correct.

Oh I got x(2/4)

x^(2/4)

It was like “John is investing $100 at a 3% annual rate compounded monthly. What expression gives the value”. Except my friends are saying it was a series question of an exponential sum but that would not really make sense. I just used A=P(1+r/n)^by and got 100(1.0025)^12

what if you used 10.3008 to get 18.6 for part b

But didn’t it say final amount of her money, so wouldn’t that mean sum of her money over that time period

Which is geometric series

U would probably get partial credit since you got the right answer

You may be right @jacobreis

@GGTRIG you should get a 5/6 on that part if that is all you messed up. The correct answer was in fact 18.6 since that is so close to 10.3002 and if you used your answer from a previous part correctly you will get full credit for the latter parts.

Also the question said that John added 100 dollars ever month

Every month

whats the question about decades to years. U just take 1/10 of whatever number was inside right and replace the d with y

Even if you got a way off answer like 20.3002 but plugged that in correctly for the latter parts they will not take off more than 1 point because you still used that correctly in the formula.

@ss1231 you would have to take .75^.1 and get whatever that was since you have to get a new rate.
