Answer : 3. ABC is less expensive by $0.05 per pound
So let's find the price for one pound first:
ABC = $6/8pounds = $0.75/ 1 pound
XYZ = $11.20/14 pounds = $0.8/ 1 pound
So we can see ABC cost less for 1 pound and we can find the difference by subtracting:
0/8=0/75 = 0.05

Answer:
f(x) = 1/25x² - 1
Step-by-step explanation:
Given that:
The quadratic function f(x) = y = ax² + bx + c
Replace (x,y) = (5,0)
0 = a5² + b5 + c
0 = 25a + 5b + c ---- (1)
The differential eqaution;dt/dx = 2ax + b at (x,y) = (0, -1) it has minimum.
Thus, dy/dx = 0
2ax + b = 0
2a(0) + b = 0
0 + b = 0
b = 0 --- (2)
Now, replace (x,y) = (0, - 1) into equation (1)
Then;
-1 = 0 + 0 + c
c = -1
From equation (1)
0 = 25a + 5(b) + c
0 = 25a + 5(0) + c
c = - 25a
a = - c/25
a = -(-1)/25
a = 1/25
Therefore; the derived quadratic equation:
y = ax² + bx + c
y = 1/25x² + (0)(x) - 1
y = 1/25x² - 1
f(x) = 1/25x² - 1
