**Question 1.**

**Solution:**

(a) y = 3x

By giving some different values to x, we shall get corresponding values of y.

x = 1 then y = 3 x 1 = 3

if x = 2, then y = 3 x 2 = 6

if x = 0, then y = 3 x 0 = 0

Now plotting the points given above, and joining them.

(b) We get a line, From the graph.

(i) When x = 3, then y = 9

(ii) When x = 5, then y = 15

(iii) When x = 6, then y = 18 Ans.

**Question 2.**

**Solution:**

(a) P = 4x

By giving some different values to x, we get the corresponding values of y or P

If x = 1, then P = 4 x 1 = 4

if x = 2, then P = 4 x 2 = 8

if x = 0, then P = 4 x 0 = 0

Plot the points (1, 4), (2, 8) and 0, 0) on the graph and join then to get the graph of P = 4x as shown

(b) From the graph we see that

(i) When x = 3, then P = 12

(ii) When x = 4, then P = 16

(iii) When x = 6, then P = 24 Ans.

**Question 3.**

**Solution:**

A = x²

giving some values to x, we get corresponding values of y or A

If x = 1, then y or A = (1)² = 1

If x = 2, then y or A = (2)² = 4

If x = 0, then y or A = (0)² = 0

Now plot the point (1, 1), (2, 4), (0, 0) on the graph, and join them to get the graph of A = x2 as shown

(b) From the graph we see that

(i) When x = 2, then A = 4

(ii) When x = 3, then A = 9

(ii) When x = 4 then A = 16 Ans.
