If you are talking about functions in 2-dimensional space, that is, functions of the sort y = f(x), then, by definition, none can be positive in the third quadrant where y is always negative.
If you are talking about functions in 3-dimensional space, ie functions of the kind z = f(x,y), then for the third quadrant in terms of x and y (x<0 and y<0), there are infinitely many functions for which z > 0.

The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
y=6x is in the third quadrant while x is negative and in the first quadrant while x is positive.
The third quadrant.
It 2-dimensional coordinate geometry, angles are measured from the origin, relative to the positive direction of the x-axis and they increase in the anti-clockwise direction. As a result, small positive angles are in the first quadrant, and as the angle size increases it moves into the second, third and fourth quadrants.
That's Quadrant - I .
The tangent and cotangent functions.
The third quadrant.
The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
If you are familiar with trigonometric functions defined in terms of the unit circle, the x and y coordinates are negative in the third quadrant. As a result, x/y, the ratio that defines cotangent, is positive.
y=6x is in the third quadrant while x is negative and in the first quadrant while x is positive.
In the third quadrant, both the x and y coordinates are negative. Since tangent is defined as the ratio of the opposite side to the adjacent side in a right triangle, in the third quadrant where both sides are negative, the tangent of an angle theta will be positive. Therefore, tan theta is not negative in the third quadrant.

There are two square root functions from the non-negative real numbers to either the non-negative real numbers (Quadrant I) or to the non-positive real numbers (Quadrant IV). The two functions are symmetrical about the horizontal axis.
Quadrant I: x positive, y positive. Quadrant II: x negative, y positive. Quadrant III: x negative, y negative. Quadrant II: x positive, y negative.
There are four quadrants. They are represented by Roman numerals : I(one), II(two), III(three), IV(four). The first quadrant contains all positive points , (+x, +y) The second quadrant contains negative x's and positive y's , (-x, +y) The third quadrant is all negative , (-x, -y) The fourth quadrant has negative y's and positive x's , (+x, -y)
The third quadrant.
It 2-dimensional coordinate geometry, angles are measured from the origin, relative to the positive direction of the x-axis and they increase in the anti-clockwise direction. As a result, small positive angles are in the first quadrant, and as the angle size increases it moves into the second, third and fourth quadrants.
