Answer:
a = 2
Step-by-step explanation:
The vertex form y = a(x - h)^2 + k
Where (h, k) is the vertex.
Given: (h, k) = (3, 6) and point (4, 8)
Now plug in the given values and find the value of "a"
x =4 and y = 8
8 = a(4 - 3)^2 + 6
8 = a(1)^2 + 6
8 = a + 6
a = 8 - 6
a = 2
So the value of a = 2.
Hope you will understand the concept.
