Hello:
an equation is : f(x) = a(x-0)² +0
the point (2 , -2)in parabola : -2= a(2-0)² +0
-2=4a
a =-1/2 is the coefficient of the squared expression in the parabola equation
<span>the vertex form is m f(x) = -1/2x²</span>
Hopes this helps:
Answer: 9
Answer:
Step-by-step explanation:
-12 = 3/4n + 8....subtract 8 from both sides
-12 - 8 = 3/4n
-20 = 3/4n.....multiply both sides by 4/3, cancelling the 3/4 on the right
-20 (4/3) = n
-80/3 = n
ur answer is A
