Answer
A) one and three fourths
Step by step explanation
y = x^2 - x + 2
Here we have to use the formula.
The x coordinate of the vertex = -b/2a
Compare the given equation y = x^2 - x + 2 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"
Here a = 1 and b = -1
Vertex of x coordinate = -b/2a, now plug in the value of a and b, we get
x = - (-1)/2(1)
x = 1/2
Now we have to find the y-coordinate of vertex.
Now plug in x = 1/2 in the given equation, we get
y = (1/2)^2 - 1/2 + 2
y = 1/4 - 1/2 + 2
y = 1 3/4
That is one and three fourths.
The answer is A) one and three fourths.
Thank you.

Answer:
-5 or 5 depending on how you write the simplified form
Step-by-step explanation:
__
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
__
Some folks like their simplified form to contain only positive exponents. Other folks avoid unnecessary fractions. Choose the form that satisfies your grader.
