what is the range of the function f(x) = 7 - x^2

OpenStudy (tkhunny):

x^2 is never negative. The least value of x^2 is zero (0). The greatest values of 7 - x^2 must be 7. Where does that leave us>

OpenStudy (anonymous):

7 because range is the highest minus the lowest number so 7-0 = 7?

OpenStudy (tkhunny):

\(y \le 7\)
