Can someone plzz help




"Find the inverse of the function, and then determine whether the inverse is a function"

Y=^3sqrt x-5

AY=x+5; inverse is a function
BY=(x+5)^1/3; inverse is a function
CY=x^3+5; inverse is a function

D.y=x^3/4+5; inverse is a function

Verified Answer :

bcalle

y = cube root (x - 5)
switch x and y
x = cube root (y - 5)
raise both sides to the third power to clear the cube root.
x^3 = y - 5
add 5 to each side
x^3 + 5 = y
y = x^3 + 5 Letter C
yes it is a function
