Question

calcular o zero de cada uma das funções:​

Answer 1

Calcular o zero ė igual a calcular a raiz das funções,que se acha igualando o Y a zero (y=0)

a) y = x/3 - 2

0 = x/3 - 2

x = 2/3

b) y = x/2 -3/4

0 = x/2 - 3/4

3/4 .2 = x

x = 3/2

Answer 2

Resposta:

$a)y=\frac{x}{3}-2\\\frac{x}{3}-2=0\\\frac{x}{3}=2\\x=2*3\\\boxed {x=6}\\\\b)y=\frac{x}{2}-\frac{3}{4}\\\frac{x}{2}-\frac{3}{4}=0\\\\\frac{x}{2}=\frac{3}{4}\\x*4=2*3\\4x=6\\x=\frac{6}{4}\\x=\frac{3}{2}\\\boxed {x=\frac{3}{2}}$
