Question

What is the equation of the line of symmetry for the graph of y = 3(x – 2)2 + 1?

a. x = –2
b. x = 1
c. x = 2
d. x = 3

Answer 1

i think its a

Answer 2

3(x – 2)^2 + 1

a(x-h)^2+k

line of symmtery is x=h

so in your case h=2 so x=2

Answer 3

its 2 o r -2?

Answer 4

what did I write?

Answer 5

b/c dont u have to take ur sign with it? you for x = 2

Answer 6

*wrote

Answer 7

yes, in general case

a(x-h)^2

symmerty line -> x=h

a(x+h)^2 =a(x- -h)^2 --> x=-h

Answer 8

so its a?

Answer 9

is it?

Answer 10

no, it is x=2

Answer 11

buy why if before it has a -

Answer 12

IF IT WERE

3(x + 2)^2 + 1

then it would be x=-2

Answer 13

oh so its the opposite sign?

Answer 14

yes

Answer 15

oh i get it thank u!
