Question

The vertex of the parabola is it 3,-2 when the xvalue is 4 the yvalue is 3 what is the coefficient of the squared term in the parabola equation

Answer 1

Answer:

5 = a

Step-by-step explanation:

Use the model y - k = a(x - h)^2, where (h, k) represents the vertex.  Here we have:

y + 2 = a(x - 3)^2

Now substitute 4 for x and 3 for y:  

3 + 2 = a(4 - 1)^2, or     5 = a
