Answer:
Vertex = 1,2
it is shifted 2 units up and to the right 1 unit
it is a downward parabola (max at (1,2) going down
Step-by-step explanation:
You can read this max y-value directly from the graph. It's 4. The vertex of this graph is at (2,4).
8.75 I think bc 1.50 x 4 = 6 then add 2.75 and you get $8.75
Answer:

Step-by-step explanation:
The equation of a quadratic function in vertex form is given by:

Where (h,k) is the vertex.
It was given in the question that the vertex of the parabola is (-1,4).
When we substitute the vertex into the formula we get:

The parabola also passes through (4,19) hence it must satisfy its equation.



We divide both sides by 25 to get:

Hence the quadratic function is:
