Question

What is the axis of symmetry of the graph of y = -3(x + 8)2 + 5?

x = -3
x = 5
x = 8
x = -8

Answer 1

can u graph it..??

Answer 2

@kellyconnelly ?

Answer 3

is y = -3(x + 8)2 + 5?
or y = -3(x + 8)^2 + 5?

Answer 4

it is squared........ she wont square it..... lol

Answer 5

second one and ill square it >:(

Answer 6

max value = 5 when x+8=0
so x=-8 is the x of the max pt,
for quadratic, graph symmetry at max pt,
so x=-8 is the answer

Answer 7

yea so what x value do u think will cut it exactly in half..?

Answer 8

how u make graphs ?
i mean software ?

Answer 10

actually this equation ald done the square completing, you can directly obtain answer in the equation without drawing graph

Answer 11

lol @neoh147 ....... yea u gave her the answer..... :D
