MAC 1105 Test 1 Review 1.4 – 1.7
You will need to have your own graphing calculator for the test. You may not share
calculators or use any type of communication device in place of a calculator. Tests cannot be made up for any reason other than an NWFSC
event for which you must miss class. If you miss one test, your final exam score will be
substituted. A second missed test is a zero.

To study for the test:
• Complete all assigned homework. Remember that a score of at least 70% on each assignment gives you 10 bonus points on the test.
• Complete the practice test and check your solutions.• Set up a study system (note cards for example) for each
of the 14 objectives in the chart above.• Review your notes and applicable problem set questions
for each of the 14 objectives in the chart above.• Work the suggested text problems for each of the 14
objectives in the chart above.
1) Write the inequality notation for each interval. You do not have to graph the inequality.
a)
c)
d)
6) Use the discriminant of the quadratic equation to determine the number and type of
solutions of the equation.
7) The height of a ball after t seconds when thrown straight up is given by the function
When will the height of the ball be 40 feet?
• You can solve this on the graphing calculator or by using the quadratic formula. On the graphing calculator:
1. Place the function in Y12. Place 40 in Y23. Graph the function using a window that is large enough to
see the curve and the two intersections. [0,10] for x and [0, 200] for y works well.
4. Use 2nd calc 5 twice to find both points of intersection. The x coordinates are the two times.
8) Use the intersection-of-graphs method to find the approximate solution to the equation. Please round
your answer to the nearest thousandth.
4) The height of a ball after t seconds when thrown straight up is given by the function
When will the ball reach a height of 70 feet?
