amplitude of-2cos(x)

Solution

amplitude

- 2 cos (x)

Solution

2

Solution steps

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

Therefore, the amplitude |A| is

2

2

Popular Examples

inverse of f(x)=4+1/3 x inverse

f (x) = 4 + \frac{1}{3} x

x = - 2

domain of f(x)=((x+5))/x domain

f (x) = \frac{( x + 5 )}{x}

shift 4sin(2x-pi)shift

4 sin (2 x - π)

intercepts of f(x)=-2x^2+24x-72 intercepts

f (x) = - 2 x^{2} + 24 x - 72
