Math 109-50, FA01
Study Guide - Exam # 1

The exam will consist of approximately 10 problems taken from the following 19 types:

1. Rationalize a numerator or denominator. (R6 # 53-72)

2. Find the domain of a function. (1.1 # 31-46)

3. Find the equation of a line, given a point and the slope, or given two points. (1.2 # 31-46)

4. Given the equation of a line, graph the line. (1.2 # 23-30 plus graphing)

5. Determine whether a given set of points would be reasonably modeled by a linear function. (1.3 # 1-8)

6. Use Maple to find where a function is increasing and decreasing, or to find local maxima and minima.  (1.4 # 5-14)

7. Graph a piecewise-defined function (all of whose pieces are linear) by hand. (1.4 # 35-42)

8. Given the formula for a function f, find   and simplify. (1.4 # 77-82)

9. Given a graph of a function, draw various variations – similar to 1.5 problems 76-83, except that I’ll ask you to draw the new function on top of the original.

10. Test a function algebraically and graphically to determine whether it's even, odd or neither; whether it's symmetric about the x-axis, y-axis, origin, or none.  (1.5 # 7-42)

11. Solve a variation problem, whether simply a formula (1.6 # 1-12, 25-34) or a word problem. (1.6 # 14-24, 35-40)

12. Given the equation of a circle in (x - h)2 + (y - k)2  = r2  format, find center and radius and graph it. (1.7 # 33-40)

13. Given the center and radius of a circle, find its equation.  (1.7 # 25-29)

14. Find the zero of a linear function (algebraically).  (2.1 # 3-34)

15. Multiply two complex numbers.  (2.2 # 11-14)

16. Solve a quadratic equation, or find zeroes of a quadratic function, using the quadratic formula. (2.3 # 11-22)

17. Solve a quadratic equation, or find zeroes of a quadratic function (2.3 # 29-36, 43-48)

18. Given a parabola in the form  y = a(x - h)2 + k, graph it by hand.  (2.4 # 11-18)

19. Given a parabola in the form  y = ax2 + bx + c, find the vertex, and using the vertex, put it in the form  y = a(x - h)2 + k. (2.4 # 3-10, 19-26)
