Question

Determine o zero de cada função:
a) f(x) = 2X + 4
b) g(x) = - 4X + 18
c) h (X) = 3x
d) m (x) = - X + 12

Answer 1

a) 2x = -4
x = -4/2
x= -2

b) -4x = -18(x-1)
x = 18/4
x = 9/2

c) 3x=0
x=0/3
x=0

d) -x=-12 (x-1)
x=12

Answer 2

a) 2x = -4

x = -4/2

x= -2

b) -4x = -18(x-1)

x = 18/4

x = 9/2

c) 3x=0

x=0/3

x=0

d) -x=-12 (x-1)

x=12
