Question

A zucchini plant in Darnell’s garden was 10 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeters per day.
a. Choose the rule that describes the function.
b. After how many days will the zucchini plant be 0.185 meters tall?

Answer 1

A) f (x) = 10 + 0.5x

B) first convert meters to centimeters
0.185 × 10 = 18.5CM
plug in 18.5 and then subtract 10 from both sides
18.5 = 10 + 0.5x
divide both sides by 0.5
8.5 = 0.5x
8.5 divided by 0.5 is 17
x = 17 days
