Explanation Given information: The logarithmic function, y = log 3 x Concept used: The equivalent exponential form of a logarithm for a > 0 , x > 0 , a ≠ 1 is given by log b x = y if and only if x = b y In a rectangular coordinate system any point is represented as ( x , y ) . It indicates that the point is at a horizontal distance of x units and vertical distance of y units from the origin ( 0 , 0 ) . A point in the first quadrant be of the form ( + , + ) . A point in the second quadrant be of the form ( − , + ) . A point in the third quadrant be of the form ( − , − ) . A point in the fourth quadrant be of the form ( + , − ) . Calculation: To plot the graph of the given logarithmic function, first we will convert it into equivalent exponent form. So we have y = log 3 x ⇒ x = 3 y Now we will find some ordered pairs that satisfy above equation by taking some random values of y and find the corresponding x -values. Then we plot these points on rectangular coordinate system and connect with a smooth curve

Question

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
