...what do you mean? That's not an inequality, that's an equation.

wdym sign

oh sorry I meant y>x^2+6x+5

crimson pagoda Mar 20, 2025, 5:37 AM

#

did you try sketching the graph?

raven wing oh sorry I meant y>x^2+6x+5

Look, why don't you just show us a picture of the question as written?

dapper rose Look, why don't you just show us a *picture* of the question as written?

I wrote it in my writing book and it says to "Solve the inequality y>x^2+6x+5"

crimson pagoda did you try sketching the graph?

no...

#

I found the factors x= -5 and x= -1 but idk what sign to put

You wrote it down wrong.

sketch the graph and first mark those x points

#

dapper rose You wrote it down wrong.

I think they mean x^2+6x+5>0

dapper rose Mar 20, 2025, 5:49 AM

#

crimson pagoda I think they mean x^2+6x+5>0

Maybe, maybe not, we don't know because they wrote it down wrong.

crimson pagoda I think they mean x^2+6x+5>0

yes

crimson pagoda Mar 20, 2025, 6:01 AM

#

raven wing

now check for where the curve is above the x axis

crimson pagoda Mar 20, 2025, 6:01 AM

#

raven wing

#

It would be this right?

raven wing Mar 20, 2025, 6:02 AM

#

oh

#

x>-1 and x<-5 ???

crimson pagoda Mar 20, 2025, 6:04 AM

#

raven wing x>-1 and x<-5 ???

yess for these qs you need to sketch the maximum or minimum curve and check which region satisfies the inequality
