Match the graphs with their corresponding functions.

• A. b - p; a - q; c - r; d - s
• B. b - p; a - q; c - s; d - r
• C. b - q; a - p; c - s; d - r
• D. b - q; a - p; c - r; d - s

Answer 1

The correct option is B

b - p; a - q; c - s; d - r

y = x is a straight line passing through origin. Its graph passes through first and third quadrants. The graph looks like

y = -x looks like y = x, it passes through second and third quadrants. Its graph looks like

To distinguish between $x^2$ and $x^4$ , we can use the below inequalities.

In the interval (0, 1) $x^2$ $>$ $x^4$ . If x $>$1, $x^4$ $>$ $x^2$ .

Both the graphs look similar.

If x $>$ 1,$x^4$ lies above $x^2$ . We can identify them using this information.
