Question 1:
For this case we have that the function is undefined or discontinuous where the denominator equals 0.
Thus, the function is undefined or discontinuous at +5 and -5.
To find the zeros of the function we match the function to zero and clear "x":
Factoring the denominator, taking into account that the roots are -5 and +5:
We multiply byon both sides of the equation:
ANswer:
Discontinuity: + 5, -5
Zero: x = 0
Question 2:
For this case we propose a system of equations:
x: Be the variable that represents the yellow fish
y: Be the variable that represents the green fish
We manipulate the second equation:
We substitute in the first equation:
So, we have 12 yellow fish in the aquarium.
So, we have 18 green fish.
Answer:
12 yellow fish
18 green fish
