domain of ln(1+x^2)

domain

ln (1 + x^{2})

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find positive values for logs:

- \infty < x < \infty

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

- \infty < x < \infty

f (x) = - \frac{1}{2} x^{2} + 4 x - 7

(4, 5), (8, 7)

f (x) = 6

(5, - 4), (5, 7)

(2, 3), (4, - 7)
