Answer: The vertex of the parabola (quadratic function) is (-2,-4)
Fourth option: (-2,-4)
Solution:
y=x^2+4x
y=ax^2+bx+c; a=1, b=4, c=0
Vertex: V=(h,k)
h=-b/(2a)
h=-4/(2(1))
h=-4/2
h=-2
y=x^2+4x
k=y=h^2+4h
k=(-2)^2+4(-2)
k=4-8
k=-4
Vertex: V=(h,k)
Vertex: V=( -2, -4)
Answer:
x=40
Step-by-step explanation:
x= 360-(273+47)
Answer:
c=0
Step-by-step explanation:
x² + 11x + 0 = y
x² + 11x + 0 = 0
U already know that y=0 by looking at the equations above,
But your worksheet never state "c", so we will take that c is 0 (look at the equations above.)
So c is just 0.
