Answer:
![{f}^{ - 1} (x) = \frac{1}{2} x - \frac{3}{2}](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20)
Step-by-step explanation:
To find the inverse of a function, first let y= f(x).
f(x)= 2x +3
Let y= f(x).
y= 2x +3
Next, make x the subject of formula.
y -3= 2x
Divide both sides by 2:
![x = \frac{1}{2} y - \frac{3}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20y%20%20-%20%20%20%5Cfrac%7B3%7D%7B2%7D%20)
Replace x with f⁻¹(x) and y with x to obtain the inverse of the function.
![\bf {f}^{ - 1} (x) = \frac{1}{2} x - \frac{3}{2}](https://tex.z-dn.net/?f=%5Cbf%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20%20-%20%20%20%5Cfrac%7B3%7D%7B2%7D%20)
Thus, the 2nd option is correct.
