Question

I have this math problem and it is: an equation in function from that reflects f(x)=3x over the line y=0.

Answer 1

`g(x) = -3x`

Explanation:

Given

`f(x) = 3x`

Required

Reflect over
`y = 0`

This means that we reflect over the x-axis

And the rule of reflection is:

`(x,y) \to (x,-y)`

Hence:

`f(x) = 3x`

Will become:

`g(x) = -f(x)`

So, we have:

`g(x) = -3x`
