Answer 2

There's a lot of useless info in this problem meant to throw you off. The only thing you need is the fact that you burn 430 calories per hour

if x is the number of hours and y is the amount of calories burned, then

y = 430*x

Answer 3

In function notation, you replace the y with f(x) to get

f(x) = 430*x

Answer 4

Let's say x = 1

f(x) = 430*x
f(1) = 430*1 ... replace every x with 1
f(1) = 430

so in 1 hour of exercise, you burn off 430 calories as expected
