An example of quadratic equation with this behavior is:
Which is sketched at the end of this answer.
A quadratic equation has the format:
It's roots are given by:
The number of roots depends on the discriminant , that is:
- If
, it has two different real roots.
- If
, it has one real root.
- If
, it has no real roots.
In this problem, it will have only positive y-values if: and
Thus, an example is:
Which is sketched below.

Answer:
The point is (15,10)
Step-by-step explanation:
Given data:
cost of card $50
x card sold for $2
y card sold for $1.50
from the above information given above we have following relation
2x + 1.50y = 50
the above equation is linear, therefore to find the point to point out the number of card sold, hit and try method should be used. select the proper point (x, y) so that after putting in above equation there result must not be greater than 50
Try for (15,10)
