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 maximum or minimum.

3. Evaluate the function at at specified value of the independent variable and simplify. F(x)=/x/-2; f(4)

4. Given f(x)=2/x-6 and g(x)=9/x-3,find (f-g)(x)

5. Evaluate the function at a specified value of the independent variable and simplify. F(x)=3x squared-squared root 2x; f(3)

6. Graph an even function.

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 squares regression line 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 ...
