ax^2 + bx + c (a in not equal to 0) is a ?Select one:a. Quadraticb. Vertexc. Domaind. None of the above

We have the following expression

This can't be a vertex, since, in geometry, a vertex is a point where two or more elements meet.

A domain is not either, since, in mathematics, the domain of a function is the set of the existence of itself, that is, the values for which the function is defined.

The Standard Form of a Quadratic Equation looks something like this:

Where a, b, and c are known values and a cannot be 0.

In conclusion, the answer is that is a Quadratic

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
