1
Pre-Calculus Flash Drill

2
See if you can identify the function that probably goes with each of these simple graphs….

4
How about these?

6
What about this one?

7
Did you know it? You are a tiger!

8
How about these?

9
and respectively

10
and finally:

12
Define an Even Function

13
Note: It is NOT enough to know the graph is symmetric with respect to the y-axis.

14
Define an Odd Function

15
Again, please note that it is NOT enough to know that the graph has origin symmetry.

16
The graph of x = a is…

17
… a vertical line.

18
The graph of y = a is…

19
… a horizontal line.

20
OK…that’s enough about graphs! Let’s move on…

45
OK…enough of the logs already!

46
The formula for the slope of a line is m = ?

48
Point slope equation of a line ?

50
Midpoint Formula = ?

52
Distance Formula=?

54
Here comes your favorite thing! Yeah! Trigonometry!

80
because:

82
(or undefined)

86
or

94
sine and cosine have to be equal!

96
Answer:

97
OK…now let’s see if you know your identities!

99
I hope you knew that one!!!

107
This one is very important!!

108
Now for a little algebra and you’ll be done!!

112
Notice there is NO “2”

114
Still no 2!

115
Last one…

116
There’s that two you wanted before!

117
If you know all this material, then you are prepared to begin calculus… All you need now is a sharp mind, a sharp pencil and a really big eraser!
