Answer:
Step-by-step explanation:
y - 7 = -4(x - 0)
y - 7 = -4x + 0
y = -4x + 7
The min or max of a parabola/quadratic function is the vertex
for
y=a(x-h)²+k
the vertex is (h,k)
so
vertex/min is at (-1,2)
h=-1
k=2
y=a(x-(-1))²+2
y=a(x+1)²+2
find a
given, (2,20) is on the graph
20=a(2+1)²+2
20=a(3)²+2
20=9a+2
minus 2 both sides
18=9a
divide by 9
2=a
y=2(x+1)²+2 is da equation
3rd one
f(x)=2(x+1)²+2
It would be -1.4f-18. I hope this helps!!
1, 4, 9, 16, 25, 36, and 49 because 1*1=1, 2*2=4, 3*3=9, 4*4=16, 5*5=25, 6*6=36, and 7*7=49
