A composite number is one that can be made by multiply two numbers to each other. Since 49=7*7, 49 is a composite number.
Check:
You can check a multiplication chart, but you will see that 49 is the only one that can be multiplied by 2 numbers
The answer to this is 384.57909
f(0)=64, f(1)=66, f(2)=72, f(3)=82, f(4)=96,...=2,6,10,14,...=2{1,3,5,7,...}
This can be written 2{2x+1}, so the intervals on which f(x) increases are 4x+2.
Answer:
I would say...
C.)x - 5 = 3 (x + 2)
Really really sorry if I'm wrong...
One thing I can say is that when it says 5 less than a #, that means the # is being subtracted from another #...
