Answer:
4 rate of change is 2/3 and the initial value is -2
5.We start with 5 gallons in the bucket and add 2 gallons per minute
Step-by-step explanation:
4. f(x) = 2/3 x -2
The initial value is when x=0
f(0) = 0 -2
f(0) = -2
The rate of change is the slope
This is in the form y = mx+b where m is the slope
m = 2/3 so the rate of change is 2/3
5. f(x) = 2x+5
f(x) is the amount of water after x minutes
This is in the form y= mx+b where m is the slope and b is the y intercept or initial value.
We start with 5 gallons in the bucket and add 2 gallons per minute
