f(x) = 2x^2+4x+1
Can someone explain how the f(x) is worked into this function?
I am supposed to graph the function and find the vertex and the axis of symmetry.I'm a little lost no major.

F(x) = Y = 2x^2 + 4x + 1.
a. h = Xv = B/2A = 4/4 = 1 = Axis of symmetry.
b. k = 2*1^2 + 4*1 + 1 = 3.
V(h,k) = (1,3).
c. Use the given Eq(Y = 2x^2+4x+1) to calculate "Y" for each value of "X" shown below.
