(a) determine, without graphing, whether the function has a minimum value or a maximum value f(x) = 2x -8x -5

The leading coefficient is positive, which means that the function has a minimum value.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

It's vertex is the point

In which

If a<0, the vertex is a maximum point, otherwise, it is a minimum point.

In this question:

So , which means that the function has a minimum value.

man its nopq i just guessed and got it right so uhh
