The graphs of the following functions are drawn:
y= 2x-1
y= 1-x2
y= (1-x)2
y=2-x
Which two graphs do not intersect?
Answer:
16) E
The best way to solve this question is to solve for ‘y’ using different values of ‘x’, draw a mini graph on your paper and plot the points accordingly. Yes, this may take a couple of minutes. So, I suggest you save this question to the end and come back to it.
You will realise that graphs 2 and 4 don’t intersect.
