Answer:
It's asking you to find the inputs of the function.
Step-by-step explanation:
Basically, when you input something, you replace "x" in the equation with the number you want to input. For example, if I had the equation: 5x/6+5, then I wanted to input "5", then 5 would replace x in the equation, making 5(5)/6+5. The output they are giving you is simply evaluating the equation that you used to input x, so basically in the case I gave you, the output would be 5(5)/6+5, or 25/6+5, and 55/6. Using the outputs, they want you to find the inputs.
 
        
             
        
        
        
40,000 is 10 times as much as 4,000
        
             
        
        
        
To find the x intercept just substitute your y value for 0 then solve for x.
So you get 0= x+3 and then you get x=-3 which is at (-3,0).
