Q. In the spring, Megan plants sunflowers in her backyard and keeps track of how tall they are. The function f(x)f(x) gives their height in inches xx days after they are planted.\newlineWhat does f(90)>55f(90) > 55 tell you?\newlineChoices:\newline(A)It takes more than 5555 days for the sunflowers to reach 9090 inches.\newline(B)The sunflowers are over 5555 inches tall 9090 days after planting.
  1. Understand Function f(x)f(x): Understand the function f(x)f(x) and what it represents.\newlineThe function f(x)f(x) gives the height of the sunflowers in inches xx days after they are planted. The variable xx represents the number of days after planting.
  2. Interpret Inequality f(90)>55f(90) > 55: Interpret the inequality f(90)>55f(90) > 55. The inequality tells us that the height of the sunflowers, 9090 days after planting, is greater than 5555 inches. It does not provide information about the time it takes for the sunflowers to reach a certain height, only their height after a specific number of days.
  3. Match Correct Interpretation: Match the correct interpretation with the given choices.\newlineBased on the interpretation in Step 22, the correct choice is that the sunflowers are over 5555 inches tall 9090 days after planting.
