What is the definition of absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. It is denoted as |x|.

FLASHCARD QUESTION

Front

How do you graph a piecewise function?

Back

To graph a piecewise function, plot each piece of the function on its specified interval, ensuring to use open or closed dots as needed.

FLASHCARD QUESTION

Front

What is the vertex of the function y = a|x - h| + k?

Back

The vertex of the function is the point (h, k), which is the highest or lowest point of the graph depending on the value of 'a'.

FLASHCARD QUESTION

Front

What does the graph of f(x) = |x| look like?

Back

The graph of f(x) = |x| is a V-shaped graph that opens upwards, with the vertex at the origin (0,0).

FLASHCARD QUESTION

Front

What is the effect of changing 'a' in the function y = a|x|?

Back

Changing 'a' affects the vertical stretch or compression of the graph. If 'a' is greater than 1, the graph stretches; if 'a' is between 0 and 1, it compresses.

FLASHCARD QUESTION

Front

What is a parent function?

Back

A parent function is the simplest form of a function in a family of functions. For absolute value, the parent function is f(x) = |x|.

7.

FLASHCARD QUESTION

Front

How do you find the x-intercepts of the function y = |x - 3|?

Back

To find the x-intercepts, set y = 0: |x - 3| = 0, which gives x = 3.
