Question

F(x) = 0.1x(x + 6)(4x + 10)
Identify the zeros of the function.

Answer 1

x=-6

x=-5/2

x=0

Explanation:

f(x) = 0.1x(x + 6)(4x + 10)

Set the function equal to zero

0 = 0.1x(x + 6)(4x + 10)

We can use the zero product property

.1x =0 x+6 =0 4x+10 =0

x =0 x = -6 4x = -10

x = -10/4

x = -5/2
