What is the correct graph of f(x) = x3 – 10x2 + 9x ?

Answer with explanation:

The Given cubic function is:

The graph will cut , x axis at three points,that is at, x=0,1 and 9.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
