Question

вычислите f (-1)-f (3)

Answer 1

f(x)=x²+√x+1,функцию лучше  так записать или условие неверно

f(- 1)= (-1)²+√ -1+1 =1 +0=1.

f(3)= 3²+√3+1= 9+2=11.

f(-1) -f(3)= 1- 11= - 10.

Answer 2

To compute the value of f(-1) - f(3), I would need to know the explicit form or definition of the function f(x). Without this information, I cannot provide the exact result.

If you can provide the function f(x) or any relevant information about it, I'll be happy to help you evaluate f(-1) - f(3).
