Answer:
Domain [2,5)
Range (-6,18]
Step-by-step explanation:
Domain is shifted 2 units to the right because of the horizontal shift so it is [2,5)
Range is multiplied by 3 because of the vertical stretch so it is (-6,18]
257,650 rounded to the nearest hundred is 257,700 because it is right at the border (50) we have to round up.
Option C:
is the slope of the line
Explanation:
The line passes through the points
and 
We need to find the slope of the line.
The slope can be determined using the formula,

Where the coordinates
and
are
and 
Let us substitute the points in the formula
Thus, we have,

Simplifying, we get,

Adding the numerator and denominator, we have,

Cancelling the negative terms, we get,

Thus, the slope of the line is 
Therefore, Option C is the correct answer.
A polynomial function is a function involving only non-negative (positive and 0) integer powers of 'x', i.e. all terms with ' 'x' have a non-negative integer power, such as a quadratic
and so on.
Option E is the answer.
Rest all are wrong answers. they do not have positive integers.
