Answer:
The answer in the procedure
Step-by-step explanation:
Let
x-----> amount corresponding to 75%
we know that
using proportion

It would be D………………………….,
Y=-x^2-2x+3 a=-1, b=-2, c=3
To find the x coordinate of the vertex, we use this formula: x=b/2a
So plug everything in and you'll get x=1.
Now plug that in the original equation to find the y coordinate.
