Question

Match the following values of y when x = 2 and x = 3 respectively and the relation between x and y.

• A. $y=x^2$
• B. $y=2x$
• C. $y=3x$
• D. $y=3x-2$

Answer 1

When $y=x^2$ and x = 2 and x = 3, $y=2^{2}andy=3^2$
i.e., y = 4 and y = 9

When $y=2x$ and x = 2 and x = 3, $y=2\times 2andy=3\times 2$
i.e., y = 4 and y = 6

When $y=3x-2$ and x = 2 and x = 3, $y=3\times 2-2andy=3\times 3-2$
​​​​​​​i.e., y = 4 and y = 7

When $y=3x$ and x = 2 and x = 3, $y=2\times 3andy=3\times 3$
​​​​​​​i.e., y = 6 and y = 9
