Piece Wise Functions Practice Test

Front

What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or formulas for different intervals of the input variable.

Front

How do you calculate the average rate of change of a function on an interval [a, b]?

Back

The average rate of change is calculated using the formula: \( \frac{f(b) - f(a)}{b - a} \).

What does g(4) represent in the context of a piecewise function?

Back

g(4) represents the value of the function at x = 4, which indicates the vertical position of the character at that horizontal position.

What is the significance of the vertical position g(x) in a piecewise function?

Back

The vertical position g(x) represents the output value of the function, which can indicate height, distance, or other measurements depending on the context.

What does the notation g(7) = 4 imply about the piecewise function?

Back

It implies that when the horizontal position x is 7, the vertical position g(x) is 4.

Front

Back

The absolute value creates a V-shaped graph, reflecting the values of y for negative inputs and scaling them by -2.

Front

What is the domain of a piecewise function?

Back

The domain of a piecewise function is the set of all possible input values (x) for which the function is defined.

Front

What is the range of a piecewise function?

Back

The range of a piecewise function is the set of all possible output values (g(x)) that the function can produce.

Front

How do you determine the intervals for a piecewise function?

Back

Intervals are determined by the conditions specified in the function's definition, which dictate which expression to use for given input values.
