you need to find those that do not go off to -∞
So, start with
A: parabola that open up -- bounded below at the vertex
B: as x gets negative, so does y. so not B
check the others -- what do you think?
Identify the function that fits the description given below.
The six functions that are bounded below.
A. y=(x-1)^2 B.y=int(x+1) C. y= -sqrt(x)
D. y=x^3+1 E. y=2- (4/(1+e^-x)) F. y=-x
G. y = -sin x H. y= |x|-2 I. y= cos x+1
J. y=(x+2)^3 K. y= -1/x L. y= e^x-2
