Question

-x^2-x+2

find the vertex

Answer 1

i no its -b/2a

Answer 2

so i did -1/2(-1)

Answer 3

i got 1/2

Answer 4

a = -1, b = -1 and vertex = -b/2a so plug the values in

Answer 5

correct

Answer 6

oops its -(-1) / -2 = -1/2

Answer 7

sorry!!

Answer 8

you have a double negative -(-1) = +1

Answer 9

its -1/2

Answer 10

here is another one -x^2-x+1

Answer 11

get the same -1/2

Answer 12

whats the second half though

Answer 13

sorry ?
pardon ??

Answer 14

like the first point is -1/2 but i need another one bc the vertex makes up two points

Answer 15

the -1/2 is the x in P(-1/2,y)
the other point can be obtained from the equation, substitute the -1/2 for x and solve for y.

Answer 16

* change to read:
the y value can be obtained from the equation, substitute the -1/2 for x and solve.
