The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
5/6 + 1/3
To add both sides need the same denominator. To give he fractions a common denominator, multiply the second fraction (1/3) by 2.
5/6 + 2/6
Add the numerators
7/6
Change into mixed number
1 and 1/6
