Pre Calc Chapter 1 Review

What are the zeros of a function?

• where the function crosses the x-axis
• where the function crosses the y-axis
• when x = 0
• when there's a 0 in the denominator

What is a characteristic of an odd function?

• end behavior is the same for both ends
• end behavior is different for both ends
• f(x)=f(-x)
• f(x) is always negative

What is a characteristic of an even finction

• f(x) = 0
• it's always positive
• end behavior is different for both ends
• end behavior is the same for both ends

True or false:
A continuous function has a removable discontinuity.

• true
• false

True or False:  If a function has a jump discontinuity it is always removable. 

• true
• false

True or False:  the limit of a function is the value it approaches from both the positive and the negative sides. For a limit to exist, both values must be the same.

• true
• false

True or False:  If a function has a removable discontinuity then the limit cannot exist. 

• true
• false

What is another way to think about the average rate of change on an interval?

• the slope of a tangent line at a point
• the slope of the secant line between 2 points
• zero
• it's not possible to find an average rate of change

Which asymptotes are determined by looking at the denominator of a function? 

• vertical
• horizontal
• slant
• none

Are these functions inverses of each other?

• Yes
• No
