Answer:
The domain is all real values
The range is all real values
Step-by-step explanation:
p = 20 - .8n
We can rewrite this as
p = -.8n +20
This is in the form y= mx+b
were -.8 is the slope and 20 is the y intercept
Plot at point at 20. The slope is -.8 = -8/10 = -4/5 Go down 4 and to the right 5 and plot another point. Then draw the line
The domain is the input values. What values can you put in for n
The domain is all real values
The range is the output values. What values do you get out for p
The range is all real values
