Answer:
Y'=3xy-3x-12
Y'=F(-2,-1)=0
Step-by-step explanation:
The function of the equation at the point (-2,-1)
is where the equation make the function go to zero:
Y'=3xy-3x-12
Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12
F(-2,-1)=[6]-[-6]-12
F(-2,-1)=6+6-12
F(-2,-1)=12-12
F(-2,-1)=0
Solving for y
3xy-3x-12=0
y=4/x+x
Making y=0
So the values make the function go to zero

Answer:
Step-by-step explanation:
-0.25x+1.75x<-1.75+2.5 x
sift terms containing x to right and constant term to left
1.75<2.5 x+0.25x-1.75 x
1.75<2.75x-1.75x
1.75<1.00 x
or 1.75 <x
or x>1.75
