Answer:
a=1
b=4
c=-1
Axis of cemetry and vertex:x=-2
Step-by-step explanation:
x=-b/2a
x=-4/2(1)
x=-2
Answer:

Step-by-step explanation:
Here we are given an equation in x and y and we are required to solve it for y
we have

subtracting 3x from each sides we get


now we divide both sides by 4 we get


Hence A) is our right answer.
Answer:
Step-by-step explanation:
The smallest zero is x=-7 with multiplicity of 1
The middle zero is x=2 with the multiplicity of 2
The largest zero is x=0 with the multiplicity of 7.
So, basically you just find the zero for each of the terms by setting em equal to 0 and then the multiplicty of it is the exponent for that particular term!
Hope this helps!
Please mark brainliest if you think I helped! Would really appreciate!
The minimum value for x is -1 so y = -5 to x<0 , y<-2
maximum value for x is 0 so y =3
the range is ]-5,-2[ + {3}
So the plants would die out
