From the graph, find the value of A, When
(i) (ii) (iii)
(i) Our point B to be plotted lies on function A = x2.
∴Here, first plotting A = x2.
Here, x = 2.
∴ Now for abscissa equal to 2, we plot the point on A = x2., ie A = 22 = 4
Hence, the value of A is 4
(ii) Our point C to be plotted lies on function A = x2.
∴Here, first plotting A = x2.
Here, x = 3.
∴ Now for abscissa equal to 3, we plot the point on A = x2., ie A = 32 = 9
Hence, the value of A is 9
(iii) Our point to be plotted lies on function A = x2.
∴Here, first plotting A = x2.
Here, x = 4.
∴ Now for abscissa equal to 4, we plot the point on A = x2., ie A = 42 = 16
Hence, the value of A is 16
