The minimum of a parabola is located at (–1, –3). The point (0, 1) is also on the graph. Which equation can be solved to determine the a value in the function representing the parabola?

Respuesta :

(-1,-3) is the vertex ==>y=k(x+1)²-3

(0,1) is a point of the parabola==>1=k(0+1)²-3==>k=4

Equation is y=4(x+1)²-3

Answer:

1 = a(0 + 1)^2 – 3 or A on edg
