range of-tan(x)

range

- 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

y = 9 x + 8

f (x) = - 3 lo g_{5} (x + 4)

2 - \frac{x}{x - 2}

y = - 3 x^{2}
