According to the y-intercept and it's behavior, the function that could have created it's graph is:
D.![F(x) = x^4 + 2x - 2](/tpl/images/0899/1537/c5f84.png)
This function has a negative y-intercept, that is, when
, y has a negative value, which means that options A and B are incorrect.
The function also points upwards, which means that the leading coefficient, that is, the multiplier of the value of x with the highest exponent is positive, hence option C is incorrect.
Thus, the function is:
D.![F(x) = x^4 + 2x - 2](/tpl/images/0899/1537/c5f84.png)

Step-by-step explanation:
There is parabola on the graph, so the function might be quadratic or 4th power. We have no numbers on axises, then let's analyze the answers:
(A) The graph is no parabola for this function.
(B) The parabola for " - x² " is opened downward.
(C) The parabola for this function is also opened downward.
(D) This one option is the answer. The y-intercept is (-2)
