Question

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

Answer 1

equation is in the form

\[y = a(x - h)^{2} + k\]

where (h,k) is the vertex

Answer 2

from here you can find the co-efficient a
