You take the amount paid and divide it by the amount of cheese. So 10.50 divided by 2.5 equals 4.2 and 12.60 divided by 3 equals 4.2 meaning that one pound of cheese costs $4.20

Answer with Step-by-step explanation:
We are given that an equation of curve 

We have to find the equation of tangent line to the given curve at point 
By using implicit differentiation, differentiate w.r.t x
 
 
Using formula :



Substitute the value x=
Then, we get 


Slope of tangent=m=
Equation of tangent line with slope m and passing through the point  is given by
 is given by 

Substitute the values then we get 
The equation of tangent line is given by 




This is required equation of tangent line to the given curve at given point.

Step-by-step explanation:
The domain is the horizontal extent of the graph. The graph extends to infinity in both directions horizontally (that's what the arrows mean). There are no "holes" because the open circle at x=-1 is matched by a filled circle at the same location.
__
The range is the vertical extent of the graph. The minimum is -3, which is included in the range. The maximum is infinity (as indicated by the up-pointing arrow).
