range of cos(4x)

Solution

range

cos (4 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 (4 x) \leq 1

- 1 \leq cos (4 x) \leq 1

Therefore the range is

- 1 \leq f (x) \leq 1

Popular Examples

range of (3x)/(2x-1)range

\frac{3 x}{2 x - 1}

range of f(x)=-2x^2+2x range

f (x) = - 2 x^{2} + 2 x

inflection f(x)=x^{1/3}inflection points

f (x) = x^{\frac{1}{3}}

parity f(x)= 1/(x-1)parity

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

critical f(x)=(ln(x))/x critical points

f (x) = \frac{ln ( x )}{x}
