Question

Jillian planted a sunflower. The height of her plant can be expressed by the following function where d represents the number of days the plant has been growing and h(d) Represents the height in inches.
h(d)= 3/7d + 5
How tall will her sunflower be after one week?

Answer 1

8 inches tall.



One week is seven days. Substitute 7 for d.

h(7) = 3/7(7) + 5

Now, just simplify.

h(7) = 3 + 5

h(7) = 8

So, after one week, Jillian’s sunflower will be 8 inches tall.
