Question

4) Dada a função f: R = R definida por f(x) = -3x + 1, determine:
a) f(-2) =
b) f(-1) =
c)f(0) =
d) f(1) =
e)f(2)=​

Answer 1

a) f(-2) = -3.-2 + 1 = 6 + 1 = 7

b) f(-1) = -3.-1 + 1 = 3 + 1 = 4

c) f(0) = -3.0 + 1 = 0 + 1 = 1

d) f(1) = -3.1 + 1 = -3 + 1 = -2

e) f(2) = -3.2 + 1 = -6 + 1 = -5
