Answer :
We are given a function of the form:
[tex]g(x)=2(x+6)^2-3[/tex]which needs to be compared to a standard form of a parabola in vertex form:
[tex]f(x)=a(x-h)^2+k[/tex]where (h,k) are the coordinates of the vertex
So, the parameter "a" (in our case "2") represents how steep the branches of the parabola are, and its sign (in our case positive) indicates that the branches of the parabola open upwards.
The parameter "h" (in our case "-6") indicates that there is a horizontal shift 6 units to the left.
The parameter "k" (in our case "-3") indicates that there is a vertical shift down in 3 units.
