domain of f(x)=(7x)/(x^2+3)

domain

f (x) = \frac{7 x}{x ^{2} + 3}

- \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

y = \frac{2 x ^{2} + x - 1}{x ^{2} + x - 2}

f (x) = 2 - x^{3}

f (x) = \frac{x + 2 sin ( x ) - 3 cos ( 2 x )}{x ^{2} + 3}

f (x) = 3 cos (x)

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