domain of f(x)=(8x^3+7x^2+20)/2

domain

f (x) = \frac{8 x ^{3} + 7 x ^{2} + 20}{2}

- \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

0.5 cos (16000 π t)

f (x) = (x - 12)^{2}

2 x - 7 y = 13

4 x + 3 y - 7 = 0, (6, - 5)

f (x) = - 14 - x
