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

f)x) is shaped like a V with the vertex at the origin so its is one of the choices.

B is also one because its |x| moved up 3 unuts
So is D.
