The miles per gallon, m, of an experimental car is given by
m(s) = 75-0.3(s/10)^2
where s is the car’s speed in miles per hour. What is the car’s miles per gallon when its speed is 100 miles per hour?
m(100) = 75-0.3(100/10)^2
m(100) = 75-0.3(10)^2
m(100) = 75-0.3(100)
m(100) = 75-30
m(100) = 45
45 mpg

What is the range of the function f(x) = (x-1)^2 when the domain is {-5, 0, 5} ?
range: {36, 1, 16}
f(-5)=(-5-1)2 | f(0)=(0-1)2 | f(5) = (5-1)2
= (-6)2 | = (-1)2 | = (4)2
f(-5) = 36 | f(0) = 1 | f(5) = 16
