f(x) = x^2-49
The x^2-49 is supossed to be in a square root but my computer will not let me type the square root Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! You can type sqrt(x^2 - 49) or surround your formula in triple curly braces or use TeX input, e.g. . The domain of f(x) is the set where the expression inside the sqrt is non-negative, i.e. (-infty, -7] U [7, infty).
