Answer:
Step-by-step explanation:
Complex numbers:
The following relation is important for complex numbers:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots such that it can be written as:
, in which a is the leading coefficient.
Has zeros −19 and −i
If -i is a zero, its conjugate i is also a zero. So
Output of 40 when x=1
This means that when . We use this to find the leading coefficient a. So
The polynomial is:
Answer:
The x-values that are approximate solution of the equation are
and
, respectively.
Step-by-step explanation:
From graph we infer that the x-values that represents a solution to the system of equations corresponds to those values of x in which both functions coincide. As we see, there are two x-values for , which are described below:
and
The x-values that are approximate solution of the equation are
and
, respectively.
