If i is a zero, -i is also a zero.
The way you get a complex zero is by taking the square root of a negative number. Taking the sqrt (-1) = + and - i
The discount price is .80x or 1-.20x.
Answer:
x = 14
Step-by-step explanation:
5x - 40 = 30
+40 +40
5x = 70
divide by 5 on both sides
x= 14
F(x) = x^3
f(-x) = (-x)^3 = -x^3
but if u factor out the negative then
f(-x) = -(x)^3
therefore it is an odd function because f(-x) = -f(x)
