inverse of f(x)=2cos(x)

Solution

inverse

f (x) = 2 cos (x)

Solution

arccos (\frac{x}{2})

Solution steps

Solve for

cos (x), y = 2 cos (x)

cos (x) = \frac{y}{2}

cos (a) = b \Rightarrow a = arccos (b)

arccos (\frac{y}{2})

Substitute

y = x

arccos (\frac{x}{2})

Popular Examples

(5, 7), (7, 14)

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

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

intercepts of f(x)=(x^3+64)/(x^2+9x)intercepts

f (x) = \frac{x ^{3} + 64}{x ^{2} + 9 x}

slope ofintercept 4x-y=3 slope intercept

4 x - y = 3

inverse of f(x)=4x+10 inverse

f (x) = 4 x + 10
