Question

identifique as leis das funçoes afim:

a.y=x-5

b.y=4-2x

c.y=1

d.y=x²-5x+6

e.y=-4 - x

f.y=x²

Answer 1

Resposta:

A, B, C e E

a)y = x - 5

y = 1.x - 5

a=1 e b = -5

b)y = 4 - 2x

y = - 2. x + 4

a = -2 e b = 4.

c)y = 1

y = 0.x + 1

a = 0 e b = 1

e)y=-4-x

y = -1.x - 4

a=-1 e b=-4
