1,2,3,4,6,7,8. This is the answer
Answer:
The interval of increase of g(x) is
.
Step-by-step explanation:
The interval of increase occurs when first derivative of given function brings positive values. Let be
, the first derivative of the function is:


The following condition must be met to define the interval of increase:

The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:

The solution to this inequation is:

Now, the solution to this expression in interval notation is: 
Answer:
1,120
Step-by-step explanation:
180/12=15
for every 15 frogs there would be one with spots
1,200/15=80
1,200 - 80=1,120
