Answer:
f(x) = x(x-1)
Step-by-step explanation:
The easy way to do this is to look at it graphically. an inverse function is reflected across the line y=x. f(x)=x(x-1) is an upward opening parabola when reflected, there are two y-values for all positive values of x. A function can only have one y for every x.
The answer is 20. Here is why: there are 4 quarts in 1 gallon and you want to know how many there are in 5. So you multiply 4 by 5 and you get 20 quarts.
Hope this helped a lot. ;-)

Answer:
(- 7, - 3 )
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ), thus
(3, - 7 ) → (- 7, - 3 )
