Answer:
<em>Maximum: (-1,9)</em>
Step-by-step explanation:
<u>Vertex form of the quadratic function</u>
If the graph of the quadratic function has a vertex at the point (h,k), then the function can be written as:

Where a is the leading coefficient.
We are given the following function:

To find the vertex, we need to complete squares. First, factor -2 on the first two terms:

The expression in parentheses must be completed to represent the square of a binomial. Adding 1 and subtracting 1:

Taking out the -1:

Factoring the trinomial and operating:

Comparing with the vertex form we have
Vertex (-1,9)
Leading coefficient: -2
Since the leading coefficient is negative, the function has a maximum value at its vertex, i.e.
Maximum: (-1,9)
Answer:
1/8(x-49)
Step-by-step explanation:
1/8x -49/8
Factor out 1/8
1/8*x - 1/8*49
1/8(x-49)
