Step-by-step explanation: Given function f(x)=
We need to write it in vertex from.
In order to write it in vertex form, we need to find the values of a, b and c for the given quadratic function.
a=1, b=-4 and x=3.
x-coordinate of the vertex = -b/2a = - (-4)/2(1) = 4/2 = 2.
Plugging x=2 in given function to get the value of y-coordinate of the vertex.
Therefore, we got vertex (h,k) at (2,-7)
Plugging values of a, h and k in vertex form
.
Therefore, vertex form is .Given parent function
According to rules of transformations,
y=f(x-m) will translate m units right and
y= f(x) - n will translate n units down.
Therefore, is the shifted 2 units right and 7 units down.Ответ:
its a
