Since the margin of error is 5%, the minimum of supporters will be less than the maximum of disapprovers.
So the third option will be correct. You cannot make certain conclusions based on this survey.
It's a linear function. We need only two points to the plotting of the graph.

Answer:
72
Step-by-step explanation:
Find the Rule :
2-1=1
3-1.5=1.5= constant
Verification :
1x1.5=1.5
2x1.5=3
9x1.5=13.5
48x1.5=72
What is the rule for input-output table?
An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (x-value) by 1.5 to find each output number (y-value)
is a linear polynomial
S<u>tep-by-step explanatio</u>n:
based on the highest power of the variables of a polynomial, it can be classified as linear,polynomial, quadratic polynomial,cubic polynomial etc.
In a linear polynomial, the highest power of the variable is 1. The general form of a linear polynomial is ax+b
In a quadratic polynomial, the highest power of the variables is 2.The general form of quadratic polynomial is 
In a cubic polynomial,the highest power of variable is 3.The general form of cubic polynomial is
.
Take the given question and simplify it

It is of the form ax+b. Hence it is a linear polynomial.
