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.

-------
Let 2003 be the zero year; then 2005 is the three year, and 2008 the 5 year.
---------------
P = ab^x
---
P(3) = ab^3 = 800000
P(0) = ab^0 = 900000

---
a = 900000
Solve for "b"::
b^3 = 8/9 
b = 2/cbrt(9) 
----
Equation::
P(x) = 900000^x
----
Ans: P(5) = 900000
