a.
To graph:
The given function where
a.

Explanation of Solution
Given information:
The current in amperes in electric circuit is
The voltage
The resistance
Graph:
Interpretation:
The given values of voltage and resistance are put the given formula then the value for current is obtained. The obtained data is plotted and hence the graph is obtained.
b.
To give the equation for the vertical asymptote and the
b.

Answer to Problem 27PPS
The vertical asymptote is
Explanation of Solution
Given information:
The current in amperes in electric circuit is
The voltage
The resistance
The given function is,
To find vertical asymptotes put the denominator equal to zero
So,
Therefore, the vertical asymptote is
There is no
Therefore, the vertical asymptote is
c.
To calculate:
The value of current
c.

Answer to Problem 27PPS
The value of current
Explanation of Solution
Given information:
The current in amperes in electric circuit is
The voltage
The resistance
Calculation:
The value of current can be calculated as,
Therefore, the value of current
d.
To find out what values of domain and range are meaningful in the context of the problem
d.

Answer to Problem 27PPS
The value of domain should be
Explanation of Solution
Given information:
The current in amperes in electric circuit is
In the problem context, current is non-negative value. Therefore, the domain should be restricted to the values greater than zero that is
