No. The sign of a function is not related with the fact that it is growing of decreasing.
If the function in the decreasing in the interval (a,b) it means that f(b) < f(a), but yet both f(b) and f(a) may be positive.
For example imagin the function y = - x. It is a straight line and it is decreasing for any interval that you take; this is (-∞, ∞).
If you take the interval (- ∞, 0) the function is decreasing but the values are positive. If you take the interval (0, ∞) the function is decreasing and the values are negative.

Answer:
Assuming the x-6 is under the square root sign, the value must be greater than 6 because you can not have 0 in the domain. That narrows it down to either B or C but since the denominator can not be anything less than 0, your answers will always be positive so that means the answer is Its domain is (6,∞)
Answer:
Step-by-step explanation:
Answer:
r= - 5/7
Step-by-step explanation:
Calculate the difference
-7 r = 5
Divide both sides of the equation by -7
r= -5/7
Therefore the solution is r= - 5/7
