Question

What is the range of the function y= -2x^2 + x

Answer 1

\(-2x^2+x=y\) is a downward opening parabola with a vertex at (1/4,1/8) so the range is all y<1/8

Answer 2

y<=1/8

Answer 3

I'm not quite sure what everyone else is talking about.

Answer 4

we dont need the domain @ranulp96 and f(x)<=x doesnt make any sense in this context. and NO not every real number is in the range @shamim . example f(x) is never equal to 50.

Answer 5

It's time for some people to go to bed I think lol.

Answer 6

Must be, I just don't see why anyone would answer if they obviously don't know the answer. I'm sure it just messes people up....
