domain of f(θ)=cos(θ)

domain

f (θ) = cos (θ)

- \infty < θ < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < θ < \infty

100 x

x + 14

f (x) = \frac{x + 1}{x ^{2} + 3 x - 40}

f (x) = 8750 \cdot 0.8 8^{0}

x + 13
