Question

If (-3,0) is a point on the graph of y=f(x) which of the following must be on the graph of y=-f(x)?

1.)(-3,o)
2.)(3,0)
3.)(0,3)
4.)(3,3)
5.)(0,-3)

Answer 1

I know that y=f(x) is the original point, and that y=-f(x) is its mirror point...and if the f is negate that means that its a reflection across the x axis...soooo...

Answer 2

but theres no -3,3

Answer 3

wouldn't it be 1

Answer 4

but thats the original point

Answer 5

cann these work like a regular equation?
like y=mx+b
cuz if so you don't do anything to the y-intercept
you just change the slope
it will go through the same point. or no?
i just haven't done these with functions

Answer 6

im not sure, not much of that makes sense and my book hasn't talked about it.

Answer 7

the lesson was just on reflections across the point of origin, x axis, and y axis.

Answer 8

Well if that is true. then it should be 1.

Answer 9

answer choice 1 that is

Answer 10

How can the original point of (-3,0) reflect across the x axis and still be the point (-3,0)? thats no clicking my brain

Answer 11

now i've gotta go school lol. later.

Answer 12

Where is (-3,0)? - The 0 is a clue!
