Operacje na funkcjach Kalkulator

Znaleźć sumę, różnicę, iloczyn i iloraz liczb $f{\left(x \right)} = 2 x - 1$ i $g{\left(x \right)} = 3 x + 5$.

$\left(f + g\right)\left(x\right) = {\color{red}\left(2 x - 1\right)} + {\color{red}\left(3 x + 5\right)} = 5 x + 4$

$\left(f - g\right)\left(x\right) = {\color{red}\left(2 x - 1\right)} - {\color{red}\left(3 x + 5\right)} = - x - 6$

$\left(f\cdot g\right)\left(x\right) = {\color{red}\left(2 x - 1\right)}\cdot {\color{red}\left(3 x + 5\right)} = \left(2 x - 1\right) \left(3 x + 5\right)$

$\left(\frac{f}{g}\right)\left(x\right) = \frac{{\color{red}\left(2 x - 1\right)}}{{\color{red}\left(3 x + 5\right)}} = \frac{2 x - 1}{3 x + 5}$

$\left(f + g\right)\left(x\right) = 5 x + 4$A

$\left(f - g\right)\left(x\right) = - x - 6$A

$\left(f\cdot g\right)\left(x\right) = \left(2 x - 1\right) \left(3 x + 5\right)$A

$\left(\frac{f}{g}\right)\left(x\right) = \frac{2 x - 1}{3 x + 5}$A
