Step-by-step explanation:
the functional graph is the line.
a functional graph is always showing the direct relationship between a value on one coordinate axis with a value in the other coordinate axis
here it is between the price in dollars (as we can understand it : per unit) and the number of units sold.
clearly, the more units we sell, the cheaper we have to make the price per unit.
the question is how many units can be sold for a given price ($60).
so, I find the given price on the price axis (in this case the vertical axis), go then along that price all the way to the right until I hit the function line, and then go straight down to the unit axis and see what value I am hitting there : 80. which means 80,000 units.
so, I can sell 80,000 units for $60 per unit.
Answer:
V = x³ - 3x² + 3x - 1
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the measure of the side )
Here s = x - 1 , thus
V = (x - 1)³
= (x - 1)(x - 1)(x - 1) ← expand the second pair using FOIL
= (x - 1)(x² - 2x + 1) ← distribute
= x³ - 2x² + x - x² + 2x - 1 ← collect like terms
= x³ - 3x² + 3x - 1
