What is an absolute value equation?

Back

An absolute value equation is an equation that contains an absolute value expression, which represents the distance of a number from zero on the number line.

Front

What does the expression |x - a| ≤ b represent?

Back

It represents all values of x that are within a distance b from a on the number line.

Front

What is the effect of increasing the value of k in the equation y = k|x + 2| - 4?

Back

Increasing k stretches the graph vertically.

Front

What happens to the graph of y = |x + k| - 4 as k decreases?

Back

The graph shifts to the right.

Front

What is the significance of the leading coefficient in a polynomial function?

Back

The leading coefficient determines the end behavior of the polynomial function.

Front

How do you determine if a number is a zero of a polynomial function?

Back

Substitute the number into the function; if the result is zero, it is a zero of the function.

What is the vertex form of a quadratic function?

Back

The vertex form is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

What does it mean for a function to be vertically compressed?

Back

A function is vertically compressed when the value of a is between 0 and 1 in the equation y = a|x|.
