Question

Esboce o gráfico da função f(x)= x ao quadrado - 10 no gráfico e dê as coordenadas de mínimo da função.

Answer 1

Oi Bia

f(x) = x² - 10 

a = 1
b = 0
c = -10

vértice

Vx = -b/2a = 0
Vy = f(0) = -10 

gráfico no anexo  

Answer 2

                                                     x²-10=y

calculando

x=0                                                                 y=0

0-10=y                                                       x²-10=0

y=-10                                                         x=√10

                                                                  x=3,16
