What is the inverse of the function f(x)=\sqrt[3]{7x-21}-3f(x)= 3 7x−21 −3f, (, x, ), equals, root, start index, 3, end index, square root of, 7, x, minus, 21, end square root, minus, 3 ?

given the equation is written in text so the signs and operators are weird, i don't understand the question but an inverse of any function can be found by switching f(x) or y with x.

For example if f(x) = 3x, then the inverse is x = 3y or y=x/3

step-by-step explanation:

a

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
