Answer: a) 3 sqdroot (2) B) 12

Explanation: Explanation is in the picture. There is an easier way to solve this which is to factor the 6. The factors would be 3 and 2. Because there are two pairs of 3s (sqdroot 3 x sqdroot 3x2), 3 will go out of the sqdroot while 2 stays in it.

Given the function f(x) = 3x, find the value of f−1(27). f−1(27) = 1 f−1(27) = 3 f−1(27) = 9 f−1(27) = 81
Mariulka [41]
Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
 
so we find f(x)=27 and the solve for x

f(x)=3x=27
3x=27
divide both sides by 3
x=9

so if f(9)=27 then f⁻¹(27)=9
problem solved

answer is 9
