Question

Вычислить значение функций f(x)=2x/x^2+1при x=1

Answer 1

$f(1)= \frac{2*1}{1^2+1}= \frac{2}{2} =1$

Answer 2

To calculate the value of the function f(x) = 2x/(x^2 + 1) at x = 1, simply substitute x = 1 into the expression:

f(1) = 2(1) / (1^2 + 1)

Now, simplify the expression:

f(1) = 2 / (1 + 1)

f(1) = 2 / 2

f(1) = 1

So, the value of the function f(x) at x = 1 is 1.
