Given fraction is

As we know fraction is not defined where denominator is equal to zero.
So let's find where denominator is zero.

We can factorize it as

So we can write given equation as

So x = 3 or x = -3.
So function is undefined at x = 3 and x = -3.
So option 3 is correct.
<h3>
Answer: 4^x+5x-2</h3>
Add up the equations and combine any like terms. In this case, the like terms are -8 and +6 which combine to -2. Everything else is unlike terms so you leave them as is.
f(x) + g(x) = (4^x-8) + (5x+6)
f(x) + g(x) = 4^x + 5x + (-8+6)
f(x) + g(x) = 4^x + 5x - 2
Answer;
Total profit is $18000
Step-by-step explanation:
Given in question
Number of unit is <em>1000</em>
Average revenue is <em>$100</em>
Average total cost is<em> </em><em>$80</em>
Fixed cost is <em>$2000</em>
Total revenue = average revenue
number of unit
Total revenue = $100
1000=$100000
Total input cost = total cost + fixed cost
Total cost = average cost
total unit
Total cost =$80
1000 = $80000
Total input cost = $80000 + $2000 = $82000
Profit = total revenue-total cost
Profit = $100000 - $82000 = $18000
Total profit is $18000
