Final answer:
The features of the given functions are linear and constant functions with specific slopes and y-intercepts.
Step-by-step explanation:
The features of the given functions are as follows:
- f(x) = 2x - 3
- g(x) = -4x + 7
- h(x) = -5
For f(x), the feature is a linear function with a slope of 2 and a y-intercept of -3.
For g(x), the feature is also a linear function with a slope of -4 and a y-intercept of 7.
For h(x), the feature is a constant function with a value of -5.
