domain of f(x)=-2x^2-x+1

domain

f (x) = - 2 x^{2} - x + 1

- \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) = \frac{5 x ^{2} - x}{2 x}

- 7 x + 4

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

f (t) = t - 2

f (x) = \frac{5 x - 7}{4}
