Question
Transcribed Image Text:The graph y =r + ux + sx² + tx° has negative y-intercept. In the context of profit for Yaster
Outfhtters coming from sleeping bags, what is the interpretation of this value?
O When no sleeping bags are produced, Yaster Outfitters makes money on sleeping bags.
O When no sleeping bags are produced, Yaster Outfitters loses money on sleeping bags.
O When a negative number of sleeping bags are produced, Yaster Outfitters makes money on sleeping bags.
O When a negative number of sleeping bags are produced, Yaster Outfitters loses money on sleeping bags.
The CEO of Yaster Outfitters want to drive up production levels of sleeping bags. Which of the
following is an appropriate advice, given that the value t in the profit model is negative.
O Yaster faces weekly losses regardless of production level, since t is negative.
O lim P(z) - 00, so increasing production without bound will lead to higher and higher profits.
O lim P(r) - -00, so increasing production without bound will lead to higher and higher losses.
O im P(z) = t is negative, so increasing production too much will lead to a weekly loss of $t.
Since the profit model is a cubic polynomial, the marginal profit is a
linear polynomial, cubic polynomial, logarithm, quadratic
polynomial or exponential function?1
The graph of marginal profit is
a parabola opening upward, a parabola opening downward, a straight line with
negative slope, or a straight line with positive slope?1

Use the models computed to find a model for the weekly profit, using z as the independent variable.
Find a linear regression model for the weekly cost data, using a as the independent variable.
P(z) =r+ ur + sz + tz
