16
Q

What the simple way of identifying a function?

A

The x-values don’t repeat

17
Q

What is function notation?

A

A way to name a function that is defined by an equation where “y” is replaced with f(x)

18
Q

What is an input?

A

A value substituted for an x-value in a function

19
Q

What is an output?

A

The result of sustituting a value into a function

20
Q

What is the vertical line test?

A

If any vertical line passes through the graph of a relation no more than once, then it is a function

21
Q

What are zeros of a function?

A

The x-intercepts of the graph of a function. The points for which f(x) = 0

22
Q

A set of ordered pairs is a …

A

Relation

23
Q

The set of x-values is called the …

A

Domain

24
Q

The set of y-values is called the …

A

Range

25
Q

Is {(-5,3), (-1,0), (3,4), (-1,2) a function?

A

No because the x-value repeats (-1)

26
Q

Is {(0,-8), (5,3), (-4,3), (9,2) a function?

A

Yes, because no x-value repeats

27
Q

What are zeros graphically?

A

The points at which the graph crosses/intersects the x-axis

28
Q

What are other names for zeros?

A

Roots, x-intercepts, and solutions

29
Q

How do you identify zeros algebraically?

A

Set the function equal to zero and solve it
