Answer:
the domain of this function is [0, 27]
Step-by-step explanation:
One way of answering this question would be to make a table of x and y values. Your x-values would be [0, 4] (that is, all x values between 0 and 4, including end points.
x y = 3x² - 6x + 3
0 3
1 0
2 3
4 27
From this table, it appears highly likely that the smallest y value would be 0, at x = 1, and that the largest would be 27 at x = 4. Thus, the domain of this function is [0, 27].
