Which function is the in inverse of f(x)=2x+3​
Ne4ueva [31]

Answer:

{f}^{ - 1} (x) =  \frac{1}{2} x -  \frac{3}{2}

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}

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}

Thus, the 2nd option is correct.
