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
y = 7

Answer:
2x^2 +3x -2
18
12
-22
-46
Step-by-step explanation:
-18x-8y-14 because you need to distribute the digits
We can find this by doing 16/2
This is equal to 8
The answer is you need 8 teaspoons of vinegar for 16 tsp of mayonnaise
