Question

anonymous · Answer

I have no idea how to do this...

anonymous · Answer

For a function: y = f(x), a stationary point is a point on the function graph where the gradient of the function is zero.

@walter20 what does a "stationary point" have to do with "turning point"?

Uh ya I'm still hella confused.

Oh, I think I understand, do you have answer choices though I am not 100% sure.

anonymous · Answer

Indeed I do

opcode · Answer

Okay, I think I understand.
Assume you have a point: $(x, y)$

opcode · Answer

Wait never mind, I do not get it...
However if you graph $\left|2x\right|-3$

You have: $(0,-3)$ is the vertex, and not other provided points are on the line graph that are given. So my guess would be B.

Okay... Thank you.
