Clarence Knox · Answer 1

The domain of y = f (x) is [0,8]

Step-by-step explanation:

Since the straight line with negative slope begins on the y-axis at (0. 9) and exits the plane at (8, 1), we get is domain from the minimum and maximum values of x for which the function is valid.

So, the minimum value of x at which the function is valid is x = 0 and the function is y = f (0) = 9. The maximum value of x at which the function is valid is x = 8 and the function is y = f (8) = 1.

So, the domain of the function y = f (x) is [0,8]
