First of all, I'm going to assume that we have a concave down parabola, because the stream of water is subjected to gravity.
If we need the vertex to be at , the equation will contain a
term.
If we start with we have a parabola, concave down, with vertex at
and a maximum of 0.
So, if we add 7, we will translate the function vertically up 7 units, so that the new maximum will be
We have
Now we only have to fix the fact that this parabola doesn't land at , because our parabola is too "narrow". We can work on that by multiplying the squared parenthesis by a certain coefficient: we want
such that:
- when we plug
, we have
Plugging these values gets us
As you can see in the attached figure, the parabola we get satisfies all the requests.
Answer:
eY is positive +0.1 therefore bagels are a normal good.
Step-by-step explanation:
Given data:
when, 10% rise in cheese price, 3% fall in bagels quantity observed
when, 10% rise in income, 1% fall in bagels quantity observed
from formula for cross price elasticity of demand, determine
As, eAB is negative, bagels $ cream cheese are complements.
By formula for income elasticity of demand,
we find that
Since eYis positive, bagels are a normal good.
