Function limits: Exercise approximation method
1 answer:
9514 1404 393
Answer:
A. 2
B. 6
Step-by-step explanation:
The attachment shows the table of values for exercises A and B.
A spreadsheet is also a useful tool for repeated function evaluation. Most spreadsheets carry about 16 significant digits, so can give good approximations down to very small differences from the limit value.

<em>Additional comment</em>
Here, the function simplifies to ...
f(x) = (2x)(x -1)/(x -1) = 2x
The simplified function can be evaluated directly at the limit value of x, with no approximation needed.
