The function f(x)=(2)(1.0)+x(0.5)2+x models the concentration of pineapple when 2 gallons of pineapple juice are added to x gallons of another juice. Find the concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice. Give the answer as a percent but do not include the percent sign (%).

Respuesta :

The concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice is 5.75

Functions and values

Given the functions that model the concentration of pineapple when 2 gallons of pineapple juice are added to x gallons of another juice as:

f(x)=(2)(1.0)+x(0.5)²+x

If the concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice, then;

f(3) = (2)(1.0)+3(0.5)²+3

f(3) = 2.0 + 3.75
f(3) = 5.75

Hence the concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice is 5.75
