Question

b)dada a função f(x)= 1/2.-3/4, calcule ​

Answer 1

Resposta:

f(0) = (1/2) . 0 - 3/4

f(0) = - 3/4

f(1) = (1/2) . 1 - 3/4

f(1) = 1/2 - 3/4

f(1) = (-1)/4

f(2) = 1/2 . 2 - 3/4

f(2) = 1 - 3/4

f(2) = 1/4

b1) $\frac{-3/4 - (-1/4)}{1/4}$ = $\frac{-3/4 + 1/4}{1/4}$ = $\frac{-2/4}{1/4}$ = - 2

b2) $\frac{1/4 - (-1/4) }{-3/4}$ = $\frac{1/4 + 1/4}{-3/4}$ = $\frac{1/2}{-3/4}$ = - 2/3
