Find the domain and range of the function.

1. f(x)= x^2-x

I got: Domain= All Real Numbers

Range= All Real Numbers > -1 (with a line under the greater than sign)

2. f(x)= 1-x^2

I got: Domain= All Real Numbers

Range= All Real Numbers < 1

(with a line under the less than sign)

Are these right? Thanks.

The second answer is correct, but the lowest possible value (Range lower limit) of x^2-x

is f(x) = -1/4, and occurs when x = 1/2
