domain of f(x)=(5x^2+1)/(x^2+x+25)

domain

f (x) = \frac{5 x ^{2} + 1}{x ^{2} + x + 25}

- \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

f (x) = \frac{1}{x + 7} + \frac{3}{x - 9}

x^{2} - 4 x - 5

15 x^{4} - 90 x^{2}

f (x) = \frac{( 2 x - 3 )}{( x - 2 ) ( x - 3 )}

f (x) = \frac{- 4}{2 x - 1}
