Question

Find the maximum or minimum of: f(x) = x2 + 4x + 4. What is the value of x that produces the maximum (or minimum)?

Answer 1

do you know how to do this?

Answer 2

no

Answer 3

it's a qudratic. the standard form of a qudratic is ax^2+ bx+ c, where a,b and c are numerical coeffients. the formula for the x coordinate of the vertex (minimum or maximum) is -b/2a. Now can you find the x coordinate of the vertaex?

Answer 4

f(x)=2x+4,let f (x)=0 so x=-2

Answer 5

you are in claculus? -2 is correct

Answer 6

thanks
