range of cos(ec)

Solution

range

cos (ec)

Solution

- 1 \leq f (x) \leq 1

+1

Interval Notation

[- 1, 1]

Solution steps

Range of

ec : - \infty < f (x) < \infty

Since the range of the basic

cos

function is

- 1 \leq cos (c) \leq 1

and

- \infty < ec < \infty

- 1 \leq cos (ec) \leq 1

Therefore the range is

- 1 \leq f (x) \leq 1

Popular Examples

domain of f(x)=sqrt(-cos(x))domain

f (x) = - cos (x)

y = x - 1

domain of f(x)=6x+10 domain

f (x) = 6 x + 10

inverse of f(x)=5x+6 inverse

f (x) = 5 x + 6

domain of f(x)=(2+tan(x))/(cos(2x))domain

f (x) = \frac{2 + tan ( x )}{cos ( 2 x )}
