Rate. 11. ( Solar panels produce electricity by collecting
energy from the sun. Over the course of a day, a
solar panel might produce a total of 1 kilowatt-hour
of electricity. Let's consider a function to describe
the electricity production of such a solar panel over
the course of a day. This solar panel function has
independent variable 1, the number of hours since
sunrise, and dependent variable, E, the total number
of kilowatt-hours of electricity produced by the
panel over those t hours.
a. Examine the three partial graphs in Figure 9.63.
Discuss each graph's characteristics in terms of
the electricity production it describes. Which
graph do you think is most likely to be the graph
of the solar panel function between sunrise and
about noon on a cloudless day? Explain your
reasoning
b. Complete the graph you selected in part (a) to
show the graph of the solar panel function over
the course of a full cloudless day, between sun-
rise and sunset. Explain why your graph has the
characteristics and shape that it does.
