Question

Which functions are symmetric with respect to the y-axis? Check all that apply.
f(x) = |x|
f(x) = |x| + 3
f(x) = |x + 3|
f(x) = |x| + 6
f(x) = |x – 6|
f(x) = |x + 3| – 6

Answer 1

what do you think

Answer 2

It can't be ones that have been moved to the left or right, right? This is the one question I don't get :(

Answer 3

true!

Answer 4

that would have a difference axis of symmetry

Answer 5

so you are left with....

Answer 6

I only see 3 of them

Answer 7

f(x) = |x| + 3, f(x) = |x| + 6, f(x) = |x + 3| – 6?

Answer 8

no last one is moved to left 3 unites so it has x=-3 as axis of symmetry

Answer 9

f(x)=|x| you missed this one the first one

Answer 10

So it's f(x) = |x|, f(x) = |x| + 3, f(x) = |x| + 6?

Answer 11

yes good job :)

Answer 12

Thanks so much!

Answer 13

np! my pleasure :)

Answer 14

Yay, I got 100%

Answer 15
