Responses

.
The minimum value of all function types is left parenthesis 0 comma 0 right parenthesis .

The range of all four function types is all real numbers.
The range of all four function types is all real numbers.

The domain of all four function types is all real numbers.
The domain of all four function types is all real numbers.

The x-intercept of all four function types is (0,0)
.

Answer 1

When comparing linear, quadratic, cubic, and exponential functions, the key feature that all four types share is:

**The domain of all four function types is all real numbers.**

This means that for each function type, you can input any real number for \( x \), and each function will produce an output. The other options do not hold true for all four function types. For example, the range can vary among them, and the x-intercept is not guaranteed to be at (0,0) for all function types.
