domain of 0.2x+45

domain

0.2 x + 45

- \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

\frac{x ^{3} - x}{x ^{4} + 4 x ^{3} + 3 x ^{2} - 4 x - 4}

h (x) = (tan (x))

f (x) = ln (16 - x^{2})

- \frac{1}{2}

f (x) = \frac{7 x - 21}{( x - 7 ) ( x + 1 )}
