Question

6) Dada a função definida por:
f(x)= 3x/2+1/4
Calcule:
a) f(1)
b)f(2)
c)f(-1)
d)f(-2)
Por favor!!!

Answer 1

f(x) = 3x/2 + 1/4

f(1) = (3 * 1)/2 + 1/4 = 3/2 + 1/4 = 6/4 + 1/4 = 7/4

f(2) = (3 * 2)/2 + 1/4 = 3 + 1/4 = 12/4 + 1/4 = 13/4

f(-1) = (3 * (-1))/2 + 1/4 = -3/2 + 1/4 = -6/4 + 1/4 = -5/4

f(-2) = (3 * (-2))/2 + 1/4 = -3 + 1/4 = -12/4 + 1/4 = -11/4
