The inverse of the function given will be:
f(x)=(x-7)^(1/3)
to get the inverse we make x the subject
let f(x)=y=(x-7)^(1/3)
y=(x-7)^(1/3)
getting the cube of both sides we have:
y³=[(x-7)^(1/3)]³
y³=x-7
thus
x=y³+7
next we replace y by x and x with f^-1(x)
thus the inverse will be:
f^-1(x)=x³+7
Answer:
1 hour and 30 minutes.
Here's how I did it:
960/3 = 220
220 = 30 minutes
220 = 30 minutes x 3 = 960
30x3=90
90 has to be converted into minutes and hours
so 90 = 1:30
