Here's the explanation ~
Zeros or roots of a function is the value of independent variable (usually x - coordinate or absicca) where the value of dependent variable (y - coordinate or ordinate) is 0.
That is :
The point where it cuts the x - axis, it has an x - coordinate = -6
Therefore, we can conclude that The zero of given function is -6

Answer:

Step-by-step explanation:
from the equation,
.
we can give different approach to the equation, but to make it simple and direct, let separate the equation by bringing all like terms to the same side i.e
.
if we integrate both side,


since the equation passes through the origin, and at the origin z=0 and t=0
we substitute this values and solve for the constant c
.
If we substitute the value of c into the equation we arrive at

if we the the natural logarithm of both sides, we arrive at
