Solution

amplitude

- 4 cos (2 x)

Solution

4

Solution steps

f (x) = - 4 cos (2 x), A = - 4

Therefore, the amplitude |A| is

4

4

Popular Examples

domain of f(x)=-700x+3500 domain

f (x) = - 700 x + 3500

domain of f(x)= 1/(sqrt(x^2-9))domain

f (x) = \frac{1}{x ^{2} - 9}

inflection f(x)=3x^2ln(x/4)inflection points

f (x) = 3 x^{2} ln (\frac{x}{4})

range of 4x^2-5x+7 range

4 x^{2} - 5 x + 7

asymptotes of f(x)= 1/(x+2)-2 asymptotes

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