range of cos(3x)

Solution

range

cos (3 x)

Solution

- 1 \leq f (x) \leq 1

+1

Interval Notation

[- 1, 1]

Solution steps

The range of the basic

cos

function is

- 1 \leq cos (3 x) \leq 1

- 1 \leq cos (3 x) \leq 1

Therefore the range is

- 1 \leq f (x) \leq 1

Popular Examples

inverse of f(x)=2(x-1)^3 inverse

f (x) = 2 (x - 1)^{3}

range of sqrt(2-4x)-3 range

2 - 4 x - 3

domain of 1/(5-x)+3sqrt(x-1)domain

\frac{1}{5 - x} + 3 x - 1

parity sin(3x)parity

sin (3 x)

domain of f(x)= 1/(1-x^2)domain

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