(a)
In the function P(n) = 0.4n +5.7, P(n) is price of n grams of vitamins. So for the function x = P(n); x is price of n grams of vitamins.
The inverse of function determine amount of the vitamins for the known price of x dollars. So answer is,
The amount of vitamins (in grams) for a price of x dollars.
(b)
Let P(n) = x, So

Replace n by x and x by n in the given equation.

Simplify the equation for x.

So inverse of function is after interchange of variables,

(c)
Substitute 8.3 for x in the inverse equation to obtain the valur of P^-1(8.3).

So answer is 6.5.
Every point on the original graph will move up 4 units. See the enclosed graph
Legend
Red: y = x^3
Blue: y = x^3 + 4
Green: A vertical line that shows that when x = 1 on the original red graph, x = 5 on the blue.
Answer:
12π
Step-by-step explanation:
The circumference is the distance you need to walk to do 1 full rotation of a shape. The formula to calculate the circumference of a circle will be
circumference =2πr
where π is a constant that equal to 3.14 or 22/7 and r is the radius of the circle (radius = 6 feet).
The circumference of this circle will be:
circumference =2πr
circumference =2π(6)
circumference =12π
Your answer would be D. -3,-7
