Answer:The last experimental design is the best of the options: 'Compare the average number of
tomatoes that are produced by 10 tomato plants that are grown in clay soil to
the average number of tomatoes that are produced by 10 tomato plants that are
grown in sandy soil''.
The first two experimental designs measure the growth of
tomato plants, which is not necessarily related to the yield of tomatoes. The
third experimental design compares the tomato yield of the two
soils with only one plant grown in each soil. Obviously, the result obtained
from this experiment would be statistically weak. The last experimental design
compares tomato yield and also uses a larger number of plants in each soil
type, so the results obtained would be of slightly greater statistical
significance.

Answer:
Step-by-step explanation:
f(4a) means everything you see x, plug that in with 4a. Doing that exactly so, we can see that below.
[plug in x=4a]
[exponent]
Since this cannot be simplified, is our answer.
The equation of the line is x=4
