Company X tried selling widgets at various prices to see how much profit they would make. The following table shows the widget selling price, x, and the total profit eamed
at that price, y. Write a quadratic regression equation for this set of data, rounding all
coefficients to the nearest hundredth.

Enter the coefficients of the regression equation:
+
Using this equation, find the profit, to the nearest dollar, for a selling price of 16.75
dollars.

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
