What is the general form of an absolute value function?

Back

The general form is y = a|x - h| + k, where (h, k) is the vertex.

Front

What does the 'a' value in the absolute value function y = a|x - h| + k represent?

Back

The 'a' value represents the vertical stretch or compression and the direction of the graph (upward if a > 0, downward if a < 0).

Front

What is the vertex of the absolute value function y = 8|x - 3| + 7?

Back

The vertex is (3, 7).

Front

How does a vertical compression by a factor of 1/9 affect the absolute value function?

Back

It makes the graph wider, reducing the steepness of the V shape.

Front

What is the effect of a negative 'a' value in an absolute value function?

Back

It reflects the graph across the x-axis.

Front

What is the vertex of the function y = |x + 4| + 3?
