Find the domain of each function f(x)=1/x
Tasya [4]

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.

MatroZZZ [7]

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
