(i) Our point C to be plotted lies on function P = 4x.

∴Here, first plotting P = 4x.

Here, x = 3.

∴ Now for abscissa equal to 3, we plot the point on P = 4x, ie P = 4 × 3 = 12

Hence, the value of P is 12

(ii) Our point D to be plotted lies on function P = 4x.

∴Here, first plotting P = 4x.

Here, x = 4.

∴ Now for abscissa equal to 4, we plot the point on P = 4x, ie P = 4 × 4 = 16

Hence, the value of P is 16

(iii) Our point E to be plotted lies on function P = 4x.

∴Here, first plotting P = 4x.

Here, x = 6.

∴ Now for abscissa equal to 6, we plot the point on P = 4x, ie P = 4 × 6 = 24

Hence, the value of P is 24
