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)

Domain : D{-∞,∞} the reals.

Step-by-step 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.

first one

step-by-step explanation:

a² + b²= c²

24² + 7² = c²

c= 25
