Answer:
The given equation is in vertex form.
Step-by-step explanation:
We have given a quadratic equation.
y-3 = 1/2(x-1)²
We have to find the form of the function.
y-k = a(x-h)² is vertex form of equation in which (h,k) is vertex of equation.
Comparing vertex form and given equation, we have
k = 3 and h = 1
Hence, vertex is (1,3).
So, the given equation is in vertex form.
