domain of f(x)=-2x^2+8x-7

domain

f (x) = - 2 x^{2} + 8 x - 7

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

\frac{x - 3}{4 - x ^{2}}

f (x) = \frac{x - 3}{x - 4}

f (x) = \frac{( x + 5 )}{x ^{2} - 25}

f (x) = \frac{1 + x - 1 - x}{x}

30 - x
