How do you determine the domain of a piecewise function?

Back

The domain of a piecewise function is the union of the domains of each piece, considering the intervals where each piece is defined.

Front

What does it mean for a function to be defined for all real numbers?

Back

It means that the function has a value for every possible input from negative infinity to positive infinity.

What is the significance of the notation f(x) = 2x + 1?

Back

It represents a linear function where the output is determined by multiplying the input x by 2 and then adding 1.
