Answer:
The formula for the vertex form is:
f(x) = a(x-h)^2 + k
Where (h,k) is the vertex.
The equation also tells us the direction of opening, which is the a value, in this case opens up because a is positive. It tells us the step pattern, which when a is equal to one is always 1,3,5. However, when the a value is a number other than one, you muct multiply the value by 1,3,5.
