If f(g(x)) = g(f(x)) = x, and<br> g(x) = 2 + In(x + 1), find f(4).

Dmitriy789 [7]

If $f(g(x))=g(f(x))=x$ , then $g$ and $f$ are inverses of one another. So we know $g(f(4))=4$ .

$g(f(4))=2+\ln(f(4)+1)=4$

$\implies\ln(f(4)+1)=2$

$\implies f(4)+1=e^2$

$\implies\boxed{f(4)=e^2-1}$

$4. \: {a}^{2} + {b}^{2} = {c}^{2}$

Step-by-step explanation:

3. the hypotenuse C squared = side A squared + side B squared. So 3 × 3=9 and 4 × 4 =16 therefore 9 + 16 =25 and the square root of 25 = 5.

4. In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
