Question

Here are two functions that model the data in the bar graph at the bottom of the previous page: $$M(x)=1.5 x+115$$ $$F(x)=1.4 x+121$$ Use the functions above to solve this. a. Write a function that models the total U.S. population for the years shown in the bar graph. b. Use the function from part (a) to find the total U.S. population in 2010 c. Does the result in part (b) overestimate or underestimate the actual total U.S. population in 2010 shown by the bar graph? By how much?

Step 1

S. population function, we need to add the male population function and the female population function. So, the total population function is: $$T(x) = M(x) + F(x) = (1.5x + 115) + (1.4x + 121)$$ Combining the terms, we get: $$T(x) = (1.5x + 1.4x) + (115 + Show more…
