To find:
Zero, domain, and range of the given function
Answer to Problem 9CYU
Zero of the given function is
Accordingly, its domain is
Explanation of Solution
Given information:
The function
Concept used:
Zero of an equation is obtained by putting it equal to 0 and then solving it for independent variable n .
Also set of all values of n is its domain and set of all values of w is its range.
Calculation:
Put in
Or,
Now on cross multiplying,
So, only zero of this equation is
Thus, after delivering 40 newspaper the weight of the bag remains 0 pound. So, the values of n may be from 1 to 40 and accordingly the values of variable w may be from 0 to 30 .
So, n may be smaller or equal to 40. So, domain of this function will be an infinite set
Conclusion:
Value
