How to algebraically find the limit of a function as x approaches infinity?

1 answer:

5 0

Well... One way you can do this is by testing a set of arrays and see the trend. If I chose to find what y1 is in (100, y1) and what y2 is in (101, y2), I would find the difference between y2 and y1. If y2 - y1 is positive, this means there is a positive relationship and y is also approaching POSITIVE infinity. A negative relation means that it is approaching NEGATIVE infinity. However, it could be approaching a single number like "4" for instance, and you just need to plug in the right number of data sets to make that educated guess.

Formula Example:
5 + 1 / (x + 1) will always approach 5 because "1 / (x + 1) will approach 0".

Hope this helps.

Dave bought a new game for $28. The tax rate was 7% How much was the tax and total price (if you can please add work I’m severel

Okay, let's find out how much the tax was by finding out what 7% of $28 is, we do this by multiplying:

$\sf 28\cdot 7\%$

Convert 7% into a decimal, we do this by dividing it by 100 because percentages are parts of 100:

$\sf 28\cdot 0.07$

Multiply:

$\sf 1.96$

So this is the tax. Add it to the original price to get the total price:

$\sf 28+1.96=\boxed{\sf \$ 29.96}$
