Write the Equation Parabola has a vertex at (2,5) and passes through the point (3,7)

Mathematics
1 answer:
spin [16.1K]3 years ago
6 0
Given a vetex (h,k) of a function parabola, the corresponding equation is:
f(x)=a(x-h)^2+k
With (h,k)=(2,5) we get the equation:
f(x)=a(x-2)^2+5
In order to find a, we use the  given point (3,7) like this:
7=a(3-2)^2+5\\7=a+5\\a=7-5=2
The equation is then:
f(x)=2(x-2)^2+5

mamaluj [8]
If the equilibrium is such that only 12000 units are sold for $27, then the total earnings from the given scenario is $324,000. The supply equation would then be,
        supply: 324000 = 6p   ; p = 324000/6 = 54000
        demand: 324000 = 69p ; p = 324000/69 = 4695.65 ≈ 4696
