Answer:
3rd answer f(x) = 3(x-8)(x+2)
Step-by-step explanation:
The x-intercepts are the points at which the parabola intersects the x-axis.
Function y = a(x - r₁)(x - r₂) is in factored form, where r₁ and r₂ are x-intercepts so if r₁ = 8 and r₂ = -2 then
y = a (x-8)(x-(-2))=a(x-8)(x+2)
For y intercept plug in (0,-48) in equation and calculate a:
-48 = a (0-8)(0+2)
-48 = a(-8)(+2)
-48 = -16a divide by -16
a = 3
Function is y = 3(x-8)(x+2)
Use PEMDAS so do (-3/2) first. and then rewrite it and keep doing pemdas
Total cans on bottom 4 shelves = 29 x 4 = 116
total cans on top 3 shelves = 42 x 3 = 126
total cans = 116 + 126 = 242 cans
-------------------------------------------------------------
used cans = 56
remaining cans = 242 - 56 = 186 cans
number of cans in each shelf = 9
number of shelves = 186/9 = 20 and 6 cans remaining
remaining 6 cans will be displayed in another shelf
total shelves = 20+1 = 21
I have read this all and see it but I think it’s the 3rd one but yea that’s one I would recommend
