Question

What is the value of the x-coordinate of the vertex of the function f(x)=(x+4)(x-2)?

Answer 1

well u see u already have 2 zeros right

Answer 2

the x coordinate of the vertex is halfway between those 2 points

Answer 3

that symmetry is always there for a parabola

Answer 4

so, it's 2?

Answer 5

find any 2 points on the parabola that have the same y coordinate... and look at their x coordinate

Answer 6

uhhh the 2 zeros are?

Answer 7

0=(x+4)(x-2)
x=?, x=?

Answer 8

what should x be so that it goes to 0

Answer 9

-4 and 2?

Answer 10

good so

Answer 11

where would the middle point be
