Problema Solution
Please help....find the inverse of the function if it exists.
f(n)=f(z)=sqrt(3z+12.
Thank you...
Answer provided by our tutors
f(z)=sqrt(3z+12)
y = sqrt(3z+12)
y2 = 3z+12 (square both sides)
y2-12 = 3z (subtract 12 from both sides)
(y2-12)/3 = z (divide by 3 both sides)
So, f-1(z) = (z2-12)/3 (for final anser substitute y back to z)
