Answer:
The value of f(5) is 3.2.
Step-by-step explanation:
It is given that f(1) = 3.2 and
Substitute x=1 in the above equation.
Substitute x=2 in the given equation.
Substitute x=3 in the given equation.
Substitute x=4 in the given equation.
Therefore the value of f(5) is 3.2.
Let the triplets' age be x, the sister's age is then x-5.
product of their age as given
xÂł.(x-5)=75749+x+x+x+x-5
x^4 - 5xÂł= 4x +75744
x^4 - 5xÂł -4x -75744=0
resolving the equation,
we get
x = 18
therefore, Age of ben,bob and bill is 18
so , age of stephanie is x-5 = 18-5 = 13
stephanie is 13 years old.
