Answer:
-2 is an output of the function.
Step-by-step explanation:
The given table is as follows:
Here, the values written on the left side of table i.e. values of are known as the <em>domain </em>values or <em>input </em>values to a function.
The values written on the right side of table i.e. values of are known as the <em>range</em> values or <em>output</em> values of the function
.
Let us consider the pairs of values:
(-6,8) then left side value is of and right side value is of
i.e. when , the output value
.
The same thing applies for all the pairs of values.
similarly for the pair (3,-2):
Left side value is of and right side value is of
i.e. when , the output value
.
So, the answer is:
<em>-2 is an output of the function.</em>
Answer:
d. x ∈ {-3, -2, 1}
Step-by-step explanation:
The word "approximate" in the problem statement suggests that the roots may not be integers. Consequently, the solution method of choice is graphing.
A graph shows the solutions to f(x)=0 to be x=-3, x=-2, and x=1, matching selection D.

<em>Comment on the problem statement</em>
Any value of x can be put into the formula and it will be a "solution." For example, f(0) = -6 is a "solution" to the polynomial function. The problem statement is not specific as to the solution(s) sought. We have had to guess that we want values of x such that f(x)=0.
