A graph which best shows the combination of both functions, c(t) is plotted in the image attached below.
What is a graph?
A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
What is a linear function?
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
This ultimately implies that, the data on a linear graph are directly proportional and as such, as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.
In conclusion, a graph which best shows the combination of both functions, c(t) is plotted in the image attached below.
