The vertex of this parabola is at (2, -4). when the y-value is -3, the x-value is -3. what is the coefficient of the squared term in the parabola's equation?

The squared term is 1/25

Step-by-step explanation:

The parabola equation in the vertex form is

where point (h,k) is the vertex and a is the squared term. In this case h = 2 and k = -4. On the other hand, we know that y = -3 and x = -3 are in the parabola. Replacing these values in the formula gives

Solving for a

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

391.6 is the correct answer
