domain of f(x)=x^2+2x-15

domain

f (x) = x^{2} + 2 x - 15

- \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

3 - x

(- 5, 6), (- 3, - 1)

f (x) = 5 x^{4} + 8 x^{3} + 2 x^{2}

f (x) = 10

(13, 0), (15, 1)
