Sagot :

Answer:
1. y=0
2. y=0
3. y=-4
Step-by-step explanation:
Since all equations are parabolas, the maximum
or minimum value is at the vertex.
1. y = (x+2)^2
vertex at (-2,0)
miminimum value: y=0
2. y=(2x-3)^2
vertex at (3/2,0)
miminimum value: y=0
=
3. y= x^2-4x
completing the square,
y+4 = x^2-4x+4
y+4 = (x-2)^2
vertex at (2,-4)
miminimum value: y=-4

Sorry po yan lang po alam ko
