I got that #1 was insufficient, but I plugged in x = 0.5 and x = -2 for #2, and they both worked with #2, because when x = 0.5, 32 > 8, and when x = -2, -1/32 > -1/8, so I checked "E", both insufficient.
I read the explanation, but I didn't quite understand what the "E" looking symbol meant.
Help highly appreciated from the quant whizzes, thanks!!
