The domain of the function is all real numbers except 2 and -1
Step-by-step explanation:
Domain is the set of inputs of a function on which the function is defined.
Given function is:

In case of a function involving fraction, the function is undefined if the denominator is zero so in order to find the domain of the function algebraically , we have to find the values on which the function will be undefined

The function will be undefined on x=-1 and x=2
So,
The domain of the function is all real numbers except 2 and -1

Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so

- The length of the fencing is 80 meters, so

Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:

Then substitute for y in the first:

b) To maximize A, find the zero of the first derivative:

So y = (80-40)/2 = 20 meters.

ie. 8x 4 = 32 people playing cribbage therfore 60-32 = 28 play chess which will be 14 games
Answer:
if the expression is 2x^3 then answer is 54
Step-by-step explanation:
2x^3
substitute in x=3
2* (3)^3
= 2*3*3*3
= 2*27
= 54
please give thanks, hit that heart button :) good luck
Add 20$ and 25$ and go along the line while adding 25 each time, at the same time do the same for 35$, the answer is the second month
