Question

determine o valor da função afim f(x)= -3x+4
a) f(0)
b) x=2
c) f(3)
d x= -2

Answer 1

f(x) = - 3x + 4

a) f(0)

f(0) = - 3.(0) + 4

f(0) = 4

b) x = 2

f(x) = - 3.2 + 4

f(x) = - 6 + 4

f(x) = - 2

c) f(3)

f(3) = - 3.3 + 4

f(3) = - 9 + 4

f(3) = - 5

d) x = - 2

f(x) = - 3.(-2) + 4

f(x) = 6 + 4

f(x) = 10
