Question

Find the vertex of the following function.
f(x) = -2x(squared) - 4x , (the -2x is squared)
Enter your answer as an ordered pair, example:
(1, -2)

Answer 1

\[-2x^{2}-4x\]
vertex is always -b/2a and f(-b/2a)

-(-4)/2(-2)--> 4/-4--> -1

Answer 2

then plug it in plug it in f(-b/2a)=f(-1) =-2(-1)^2-4(-1)-->-2+4-->2 so (-1,2)

Answer 3

thanks

Answer 4

welcome:)
