The vertex of this parabola is at (-3,-1). when the y-value is 0, the x-value is 4. what it the coefficient of the squared term in the parabolas equation?

Fot this parabola the coefficient for squared term is 7

Step-by-step explanation:

The formula for vertex equation is:

if vertex is at (-3,-1) and in the formula the vertex is (k,h), we replace this values

The other point of this parabola is (4,0), so we replace it in the formula below:
