range of f(x)=-tan(x)

range

f (x) = - tan (x)

- \infty < f (x) < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The range of the basic

tan

function is

- \infty < tan (x) < \infty

- \infty < tan (x) < \infty

Multiply the edges of the range by:

- 1

- \infty < - tan (x) < \infty

Therefore the range is

- \infty < f (x) < \infty

f (x) = x^{2} + 4 x + 7

f (x) = \frac{1}{2} cot (4 x)

\frac{x ^{2} - 1}{x + 2}

x

y = - 5 x + 2, (- 1, 4)

What is the range of f(x)=-tan(x) ?
The range of f(x)=-tan(x) is -infinity <f(x)<infinity
