Determine whether the following function is a one-to-one function,and if the function is a one-to-one, find a formula for the inverse.
F(x)=x^3-27
yes it is
1: y = x^3 - 27 ----> x = y^3 - 27
2: x = y^3 - 27
y^3 = -x - 27
y = (-x - 27)^(1/3)
F(x)=x^3-27
1: y = x^3 - 27 ----> x = y^3 - 27
2: x = y^3 - 27
y^3 = -x - 27
y = (-x - 27)^(1/3)
