Question

у=1/2 х²+4 график помогите решить и построить ​

Answer 1

Explicație pas cu pas:

$y = \dfrac{1}{2} \cdot x^{2} + 4$

$\Delta = 0 - 4 \cdot \dfrac{1}{2} \cdot 4 = - 8$

$V\bigg(\dfrac{-b}{2a};\dfrac{-\Delta}{4a}\bigg) \implies V\bigg(0;4\bigg)$

$x = - 2 \implies y = 6$

$x = 2 \implies y = 6$
