(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.
Answer:
Reinaldo es ingeniero
Step-by-step explanation:
Por los datos del problema sabemos que Jeferson es casado. También sabemos que el profesor se casará pronto, así que:
Jeferson no es profesor
Reinaldo debe tomar el metro para visitar al médico, así que no es vecino de ninguno. Como el médico y el profesor son vecinos, entonces Reinaldo no es médico ni profesor, asi que
Reinaldo es ingeniero
Podemos saber además que si Jeferson no es profesor (ya demostrado) ni tampoco es ingeniero, entonces
Jeferson es médico
Por descarte, Yasir es profesor
