Graph Of The Cubic Function
The cubic function can have one or three real zeros. Each zero corresponds to a point in the x-axis where the value of y is zero. When the coefficient of the cubic term is positive, the function is increasing, then decreasing and finally increasing.
The given function is
f(x)=(x - 3)(x - 1)(x + 1)
There are no options to choose from but I'm including a graph with a plot of f(x) plus the table of values to improve the sketch with more details. The zeros, maximum and minimum values can be clearly seen
Answer:
He should charge 15.75
Step-by-step explanation:
Markup = original price * markup rate
Markup = 9*75%
= 6.75
The new price is the original price plus the markup
New price = original price + markup
New price = 9+6.75
= 15.75
He should charge 15.75
p= popcorn
x=number of kids in class
c= cost
Plug in data:
c = px
31.5=1.5x
Divide both sides by 1.5:
21= x
There are 21 kids in the class.
