Solution :
= k.n (cost proportional to quantity)
35000 = k . 700
k =
= 50
So = 50 n
Now (cost proportional to square of n)
3430 = 490000 P
Now, (fixed)
Therefore,
Total,
Answer:
y = x² - 7
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (0, - 7), thus
y = a(x - 0)² - 7
To find a substitute (4, - 3) into the equation
- 3 = a(4 - 0)² - 7, that is
- 3 = 16a - 7 ( add 7 to both sides )
4 = 16a ( divide both sides by 16 )
a = , thus
y = x² - 7
