Answer:

a straight line: y = x -5, with a hole at (4, -1)

Step-by-step explanation:

The rational function can be simplified to ...

$f(x)=\dfrac{x^2-9x+20}{x-4}=\dfrac{(x-5)(x-4)}{(x-4)}\\\\f(x)=x-5\qquad\text{$x\ne 4$}$

The graph of this is a straight line, with a hole at x=4, where the function is not defined.

Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'

Part 3) The cost per pound is:
