Question

4- O vértice da função quadrática do f(x) = x2 - 7x + 10, é:​

Answer 1

Resposta:

$V(\frac{7}{2},\frac{-89}{4})$

Explicação passo-a-passo:

f(x) = x² - 7x + 10

$x_V = -\frac{b}{2a}\\y_V = -\frac{\Delta}{4a}\\\\x_V=\frac{-(-7)}{2} \\\\x_V= \frac{7}{2} \\\\y_V=\frac{-[(-7)^2-4.1.10]}{4.1}\\\\y_V=\frac{-[-49-40]}{4}\\\\y_V =\frac{89}{4} \\\\V(\frac{7}{2} ,\frac{89}{4})$
