The ideal temperature for a pet leopard gecko's enclosure is 88° F, with a maximum variation of 6° F allowed for its health. A blue-tongue skink is introduced, which requires an average temperature of 85° F and can tolerate a variation of up to 5° F. Which absolute value equation could be used to determine the range of temperatures that would be suitable for both reptiles?

Which statement best describes the effects on the graph of f(x) = |x|, when f(x) is replaced by 2f(x) - 4?

Back

The graph is vertically stretched by a scale factor of 2 and shifted down 4 units.

Front

What is the definition of an absolute value equation?

Back

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

Front

How do you solve an absolute value equation?

Back

Isolate the absolute value expression and set up two separate equations: one for the positive case and one for the negative case.

Front

What is the vertex of a parabola?

Back

The highest or lowest point on the graph of a quadratic function, depending on the direction of the parabola.

Front

What does it mean for a graph to be vertically stretched?

Back

The graph is pulled away from the x-axis, making it taller, typically by multiplying the function by a factor greater than 1.

Front

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

Back

The graph is pushed towards the x-axis, making it shorter, typically by multiplying the function by a factor between 0 and 1.
