7*7=49
since B is 7 times greater than A, so 7*7
So 3^X= 2 is an exponential equation. The inverse of an exponential in ln. so take ln of both sides to solve.
Another way is to change the exponential into a log equation
So that would be log with base 3 to the power of 2 equals x.

Answer:
1st option
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x being the inverse h(x)
h(x) =
=
x -
