1. Not a function. There are 2 outputs when x=5
2. Any values will work since there are no repeat x values
3. Your graph should circle back and not pass the verticle line test
4. s = f(h)
5. Probably not a function, since you could have 2 cars with the same horsepower have the different max speed, depending on the weight of the car or other factors.
6. Maximum speed would be around 150 mph or so
7. Threw out, since the board example was not clear
8. Graph goes through these points: (2,0), (3,3),(5,3), (6,4), (7,4), (9,0)
9. y = 3x + 1
10. a: slope
b: y intercept
c: the slope gets more steep
d: the slope slants down from left to right
e: the entire graph is shifted up 3 units
11. The graph goes through (0,-2) and has a slope of -2/3, to passes through (3,-4) and (-3,0)
12. they are parallel or the same line
13. 26(26)(26)(10)(10)
14. 5(5)(26)(10)(4)
