There are two functions that can be used to describe the percent of people 25 years and older who have completed at least high school. For both functions f(x)=0.44x + 87.5 and g(x)=0.008x^2 + 0.42x + 87.5 is the number of years since 2008, and any y (or f(x) or g(x)) is the percent of people 25 and older completing at least high school. Assume that the trend of g(x) continues. Find g(15) and describe in words what this means.

g(15)=

see the explanation

Step-by-step explanation:

Let

x ----> the number of years since 2008,

g(x) ----> the percent of people 25 years and older who have completed at least high school

we know that

so

For x=15 years since 2008

substitute

That means

In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%

sorry if im wron

Step-by-step explanation:

4y + 9

4(8) + 9

4 x 8 = 32

32 + 9 = 41

41 divided by 7 = 5.8 or 6
