In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)
The Domain is the first number of the pair D= -7, -6, -5, -4 The Range is the second number of the pair R= 5, 1, 0, when a number repeats like the number one you can put it once.
