Algebra 1 PRACTICE TEST on Absolute Value Functions & Sequences

Front

What is the definition of an absolute value function?

Back

Front

What is the general form of an absolute value function?

Back

Front

How does the parameter 'a' affect the graph of an absolute value function?

Back

The parameter 'a' affects the vertical stretch or compression and the direction of the graph. If 'a' is positive, the graph opens upwards; if negative, it opens downwards.

Front

What does the term 'vertex' refer to in the context of absolute value functions?

Back

The vertex is the highest or lowest point of the graph, depending on the direction it opens.

Front

What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

What is the formula for the nth term of a geometric sequence?

Back

Front

How do you find the common ratio in a geometric sequence?

Front

What transformation occurs when the graph of an absolute value function is shifted down by 4 units?

Back

The entire graph moves down 4 units, changing the vertex's y-coordinate.

Front

What does it mean for a geometric sequence to 'compress' or 'stretch'?

Back

'Compress' means the terms are closer together, while 'stretch' means they are further apart, affecting the growth rate of the sequence.
