(a) For the function
, the zeros of the function are the value of 
, when 
.
Solving
by grouping and factorizing gives 
Therefore, the zeros of
are 
and 
(b) For the function
, the zeros of the function are the value of 
, when 
or 
.
Recall that
.
So, we have
Equating the exponents, we have
.
Therefore, the zero of
is at 
.
(c) For the function
; 
, the zeros of the function are the value of 
between 0 and 
, where 
or 
.
For n = 0,
For n =1,
For n =2,
which is greater than 
.
Therefore, the zeros of
; 
are 
and 
.
Hi,
Zero of a function is a domain where the range of that function is zero. There may be multiple Zeros of a function depending upon the degree of that polynomial function and time period for geometric function.
