Question

draw the graph of Y = |x^2-3|

Answer 1

This answer you can do in graph otherwise I don't help you because it is the graph question.

Answer 2

take values for x as -2,-1,0,1,2 etc....find corresponding y values like y = |_2 raised to power 2 -3|= |4_3| = 1.
points to be plotted will be (_2,1),(_1,2),(0,3),(1,2),(2,1)......on plotting in a graph sheet we will get an inverted parabola (inverted U)...
