Question

Find the maximum or minimum of the following quadratic function: y =x^2 - 10x + 25.

Answer 1

first write down the first derivative of the equation (differentiate it..)

Answer 2

Sorry, may you explain?

Answer 3

Have you studied differentiation?
y=x^2-10x+25

so dy/dx = ?

Answer 4

I think he's referring to the vertex of the parabola.

Answer 5

That is true - my method is to set dy/dx=0

Answer 6

@dumbsearch2
There are other methods - have you studied ways to find the vertex?
