option c is the answer....
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
Ok, let's try to find the value of the dividend based on the given information
=> 30 is the divisor
=> The dividend is a 3 digit number, which is the least
=> Remainder of 8
To get the answer, let's find the least number that can be divided with 30
=> 30 * 1 = 30
=> 30 * 2 = 60
=> 30 * 3 = 90
=> 30 * 4 = 120, the least 3 digit number that is divisible with 30
Now, let's add 8 as a reminder
=> 120 + 8 = 128
=> 128//30 = 4 reminder 8
Hope this helps you =)
