Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
Good job oh my God you are so smart oh my God a good job bro
Answer:
The mode would be 45.
Step-by-step explanation:
The mode is 45 because a mode is the most repeated number in a set.
0/2=0 because anything divided by zero is zero.
