Hey I was trying to find this online but was not able to. Can a relative min or max be a x or y intercept? Something about it feels off if it can be.

(0,0)?

#

I think if im understanding it correctly

Right. Which is the origin, making it literally both the x-intercept and the y-intercept.

My problem im working on is f(x) = -x^3 -3x^2 +4. But im getting the min and max to both be the intercepts at x=(-2,0) and y= (0,4). So just wanted to make sure is all. seemed odd kind of.

#

Neat way to look at it though

#

...what do you mean, "x = (-2, 0)"?

#

x is... a number, it can't equal an ordered pair.

#

as in one of the x intercepts is that coordinate

#

sorry for the wording

rain sky
#

I mean, I guess it technically depends on what you mean by "intercept".

grim prism
#

Well that the x intercepts on their own will be x=1 and x=-2, but as points its (1,0), (-2,0)

#

if that makes sense

No, I mean it depends on if an x-intercept is a point that touches the x-axis or a point at which the graph crosses the x-axis.
