Question

1. dada a funçao y=3x-4 coloque y para:
a) x=2
b) x=0
c) x=5
d) x=20

Answer 1

x = 2
y = 3x - 4
y = 3.2 - 4
y = 6 - 4
y = 2
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
b)
x = 0
y = 3x - 4
y = 3.0 - 4
y = 0 - 4
y = - 4
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
c)
x = 5


y = 3x - 4
y = 3.5 - 4
y = 15 - 4
y = 11
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
d)
x = 20

y = 3x - 4
y = 3.20 - 4
y = 60 - 4
y = 56
