Answer:
D) The maximum value of the function is equal to the y-intercept.
Step-by-step explanation:
A is not correct. It should read "There are two x-intercepts and one y-intercept".
B is not correct. It should read "The curve crosses the y-axis at (0,6)".
C is not correct. Firstly, the graph has no minimum, only a maximum. Secondly, this isn't always true, to begin with.
D is correct. Like I said in answer C, the graph only has a maximum, and that maximum does indeed equal the y-intercept which I said in answer B was (0,6).
