domain of f(x)=(4x^2+4)/(2x^2+8)

domain

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

- \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

- 9 x + 2

26 x^{2} + 80 x + 64

f (x) = \frac{x + 1}{x ^{2} - 3 x}

f (x) = 2^{a r c s i n (x)}

V (x) = - 12 x^{2} + 96 x - 84
