Question

Which function has a vertex at the origin?

f(x) = (x + 4)2
f(x) = x(x – 4)
f(x) = (x – 4)(x + 4)
f(x) = –x2

@Michele_Laino

Answer 1

hint:
the origin is the point \((0,0)\)

Answer 2

i don't have no clue what this one is

Answer 3

so it would be the last one right?

Answer 4

for example, if I replace \(x=0\) into the first equation, I get:
\(f(0)=(0+4)^2=4^2=16\) so the point \((0,0)\) doesn't belong to that graph
Yes! the last option

Answer 5

like Michele_Laino said the orgin is 0,0 like on a graph
