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

Answer:

$g(x) = -3x$

Step-by-step 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:

$g(x) = -3x$
