Answer:
Step-by-step explanation:
The function is f(x) = -4x²+10x-8
Let Δ be our the dicriminant
- Δ= b²-4ac
- b = 10
- a = -4
- c = -8
- Δ = 10²-4*(-4)(-8)
- Δ = 100-128
- Δ = -28
The value of the discriminant is -28 and since it is negative this function has no real zeroes
The discount was 85% off.
The area of the mirror (v) is 9.5x7.5=71.25 inches
