Step-by-step explanation:
Use the formula (
b

)
^2 in order to create a new term. Solve for x by using this term to complete the square.
Answer:
Domain is all the possible x-values that can be plugged in and range is all the possible y-values that can be outputs. f(x)=1x can have any number as an input except for zero. If we plug in zero for x , then we would be dividing by zero which is impossible. Thus the domain is all real numbers except for zero.

Answer:
slope = -1/2 and y-intercept = 80
Step-by-step explanation:
A water tank has 80 gallons of water. But the tank has a leak from which water flows at a rate of 1 gallon every 2 minutes
Rate of change is the slope
Given that rate of change is 1 gallon every 2 minutes that is 1/2. The water flows out at the rate of 1/2. since it flows out the slope is negative.
So slope = -1/2
y intercept is the initial amount of water in the tank
A water tank has 80 gallons of water. so y intercept is 80 gallons of water
y intercept = 80
