Explanation Given: The function f ( x ) = 2 x − 4 and f − 1 Graph: In order to plot the graph of f ( x ) = 2 x − 4 , replace f ( x ) substitute y at the place of f ( x ) and evaluate the value of y variable for each value of x variable or the value of x variable for each value of y variable: To find the value of y -intercept, substitute x = 0 as shown below: y = 2 x − 4 = 2 ( 0 ) − 4 = 0 − 4 = − 4 To find the value of x-intercept, substitute y = 0 as shown below: y = 2 x − 4 0 = 2 x − 4 2 x = 4 x = 2 Hence, plot the intercepts ( 0 , − 4 ) and ( 2 , 0 ) and draw a line passing through these points to get the graph of equation f ( x ) = 2 x − 4

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.
