amplitude of-4cos(1/3 x)

Solution

amplitude

- 4 cos (\frac{1}{3} x)

Solution

4

Solution steps

f (x) = - 4 cos (\frac{1}{3} x), A = - 4

Therefore, the amplitude |A| is

4

4

Popular Examples

domain of f(x)=(x+4)/(2x)domain

f (x) = \frac{x + 4}{2 x}

domain of y=sqrt(x+2)domain

y = x + 2

monotone (5(x^2-1))/(x^2-4)monotone intervals

\frac{5 ( x ^{2} - 1 )}{x ^{2} - 4}

domain of (x^2-7)/(x+3)domain

\frac{x ^{2} - 7}{x + 3}

intercepts of f(x)=x^2-6x+1 intercepts

f (x) = x^{2} - 6 x + 1
