Question

Consider the function fx) = -3.15x + 723.45. Graph it on the interval (0,25), and then answer Questions 8 - 11 below. Question 8 (1 point) What is the domain of the function (the entire function, not just the part you graphed)? O [-3.15, 7.42) [-10, 10] [7.42, c) O 10,co)

Answer 1

Domain : D{-∞,∞} the reals.

Explanation:

The function is plotted in the image.

[tex] f(x) = -3.15 * x + 723.45 [tex]

the linear functions usually have a domain from - infinite to infinite, the domain when is a piece wise function or discontinuous, the domain is defined in the pieces where is defined.

In this case there is no restriction so the function is continuous.
