Question

PLEASE HELP - 20 POINTS!

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)=0.46x + 87.7 and ​g(x)=0.008x^2 + 0.43x + 87.7​, x 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(14​) and describe in words what this means.

​- g(14​) = [insert answer here]

Answer 1

g(14)=0.008(14)^2+0.43(14)+87.7

g(14)=0.008(196) + 6.02+ 87.7

g(14)= 1.568+ 93.72

g(14)= 95.288

g(14) means 14 years after 2008, which is the year 2022.

B) In the year 2022, 95.288% of people 25 and older will have completed at least high school.
