Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4

Answer:
Step-by-step explanation:
Given that Jared invested some money in a company's stock. Luckily for Jared, the company became very popular and the value of Jared's investment this morning is 7 times as large as the value of his investment yesterday morning.
a) Suppose Jared invested amount P
Today its value is 7P
i.e. 700% of yesterday value is value of Donald's investment this morning
b) Increase in value in one day from yesterday to today = 6 times P
i.e. increase in percent = 600%
Change in investment = +600%
The time would be 7pm because if you multiply 7/8 by 2 it would equal 14/16 then you can add hours and subtract one 1/16 at a time until you have 4/16 aka 1/4
