oh im so sorry, i made a mistake.

Answer 2

for x>= 3

Answer 3

i think F(x) is constant, b'cos it's derivative is '0'.

Answer 4

would that be no interval?
i entered 'none' in my homework and its wrong.

Answer 5

if that is true, than we need to find monotonicity of \[f(x)=9\div \ln (4t)\]

Answer 6

what does that mean?

Answer 7

it mean we need to find that wheher this function is increasing or decreasing.
