Question

there are two functions that can be used to describe the percent of americans 25 and older who have completed an associates degree or higher. for both functions f(x)=0.74x + 41.1 and g(x)=0.03x² + 0.48x + 40.7, x is the number of years since 2010, and any y (or f(x) or g(x)) is the percent of americans 25 and older who have completed an associates degree or higher. find f(9) and describe in words what this means.

find f(9)

f(9)=□
(type an integer or decimal rounded to two decimal places as needed.)

Explanation:

Step1: Substitute x = 9 into f(x)

Given f(x)=0.74x + 41.1, substitute x = 9. So we have f(9)=0.74×9 + 41.1.

Step2: Calculate 0.74×9

0.74×9 = 6.66.

Step3: Calculate f(9)

f(9)=6.66+41.1 = 47.76.

Answer:

47.76
