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

domain

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

f (x) = x^{2} + 2 x - 9

- \frac{2}{5}

f (x) = 2 x - 8, - 2 \leq x \leq 10

f (x) = - - x - 2

f (x) = - \frac{1}{2} (x + 4)^{2} + 8
