Evaluating Piecewise Functions

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 its domain.

How do you evaluate a piecewise function at a specific point?

Back

To evaluate a piecewise function at a specific point, determine which interval the point falls into and then use the corresponding expression to find the function's value.

What does it mean if a piecewise function is undefined at a certain point?

Back

If a piecewise function is undefined at a certain point, it means that there is no output value for that input, often due to the input not falling within any defined interval.

Evaluate h(5) if h(x) = { 3 for x < 0; 7 for 0 ≤ x < 10; -25 for x ≥ 10 }

Back

h(5) = 7.

Evaluate f(4) if f(x) is defined as follows: { -1 for x < 0; 0 for 0 ≤ x < 5; 5 for x ≥ 5 }

Back

f(4) = 0.

What is the output of g(-2) if g(x) = { 7 for x < -1; -1 for -1 ≤ x < 0; 1 for x ≥ 0 }

Back

g(-2) = 7.

Front

Evaluate f(0) if f(x) = { -3 for x < 0; 4 for 0 ≤ x < 5; 18 for x ≥ 5 }

Back

f(0) = 4.

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-values) 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 (y-values) that the function can produce.
