Answer:
hole at x=-3
Step-by-step explanation:
The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)
The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.
So anyways we have (x+3)/(x^2-9)
= (x+3)/((x-3)(x+3))
Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.

solved by graphing
Step-by-step explanation:
since we have the relation (inches/dollars)
4.3 inches down per dollar
per 10 dollars 43 inches down
per half a dollar 2.15 inches down
per 63.60 dollars 273.48 inches down
