7. A store owner wants to know the demand for family special as a function of price. Daily sales for four prices are listed.
Price,x $9.50 $10.25 $10.75 $11.75
Demand,y 33 26 27 28
Use a least squaresregressionline to estimate the demand for family special at $12.75

1. GIVEN f(X)=16-X SQUARED,AND G(X)=4-X, FIND F/G (x).

2. FIND THE MAXIMUM OR MINIMUM VALUE OF THE QUADRATIC FUNCTION
F(X)-X SQUARED+10X-19. STATE WHETHER THIS VALUE IS A MAX.. OR MINI..

achieves maximum 6 at x=5. Why? Since

3. EVALUATETHE FUNCTIONAT AT SPECIFIED VALUE OF THE INDEPENDENT VARIABLE AND SIMPLIFY. F(X)=/X/-2; F(4)

So,
F(4)=4-2=2

4. GIVEN F(X)=2/X-6 AND ...
