Question

determine os zeros da funçao a seguir a) y = 5x+2 b) y = -2x

Answer 1

a)

5x + 2 = 0
5x = -2
x = -2/5

b)

-2x = 0
x = 0/-2
x = 0

Answer 2

a) y = 5x+2

Zero da função : y = 0

5x + 2 = 0 ==> 5x = - 2 ==> x = - 2/5
===================================================

b) y = - 2x


Zero da função : y = 0

-2x = 0 ==> x = 0
