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

domain

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

y + 2 = \frac{5}{2} (x + 1)

(- 4, 1), (2, 4)

f (x) = 10 x + 1

2 x^{2} - 3

\frac{x - 7}{x + 7}
