Given f(x) = [(x^2 -2x -15)/x-5], notice it is a rational
function
But the numerator x^2 -2x -15 could be factored, which
yields
(x – 5)(x + 3)
Therefore f(x) = (x – 5)(x + 3)/ (x-5)
Cancelling x-5, f(x)
= x + 3
In this way, the f(x) is continuous at any point, and is
basically a line.

Answer:
the water to be added is 0.2 L
Step-by-step explanation:
The computation of the water to be added is given below:
The banberry amount is
= 7% of 6 Liters
= 0. 42L
Now
Let us assume the amount of water added be x L
So, the total solution is
= 6+ x L
Now percentage of banberry is
= 0.42 × 100 ÷ (6+x)
5 = 0.42 × 100 ÷ (9 + x)
9 + x = 9.2
x = 0.2 L
hence, the water to be added is 0.2 L
Distribute the 3a^n to all the other values then solve...
(3a^n*a^n)+(3a^n*a^n)+(3a^n*-1)
4a^2n+4a^2n-3a^n=
8a^2n-3a^n
Slope is 7/4 y intercept is -10
