Question

b. identify the output variable. the output variable is c. c. use f to represent the function and rewrite c = 0.449m using function notation. f(m)=0.449m d. the average number of miles driven per year is 20,000. evaluate f(20,000) and write a sentence describing its meaning. (simplify your answers.) f(20,000)= it costs a total of $ to own a small sedan and drive it 150,000 miles if you drive 20,000 miles per year. a. f(20,000)= it costs $ 8980 per year to own a small sedan and drive it 20,000 miles. write the result as an ordered pair. (type an ordered pair, using integers or decimals. do not use commas in the individual coordinates.)

Explanation:

Step1: Recall function - evaluation formula

We have the function $f(m)=0.449m$. To find $f(20000)$, we substitute $m = 20000$ into the function.

Step2: Perform the substitution

$f(20000)=0.449\times20000$.

Step3: Calculate the result

$0.449\times20000 = 8980$.
The ordered - pair for a function $y = f(x)$ is of the form $(x,y)$. Here, $x = m$ and $y=f(m)$. When $m = 20000$ and $f(20000)=8980$, the ordered pair is $(20000,8980)$.

Answer:

$(20000,8980)$
