X^3 -9x+1= 0 (minus 1)
X^3-9x=-1 (divide by 9)
x^3-x=-1/9
But it doesn’t work any further so you have written it wrong
Answer: OPTION D.
Step-by-step explanation:
Below are some transformations for a function f(x):
If
, then the function is reflected over the x-axis.
If
, then the function is reflected over the y-axis.
If
and
, then the function is horizontally compressed.
If
and
, then the function is horizontally stretched.
In this case you know that the parent function is:

According to the information given in the exercise, the parent function IS horizontally stretched by a factor of
and it is also reflected over the y-axis.
Therefore, based on the transformations explained before, you can notice that the transformation is:
Where 
Therefore, the equation of the transformed function is:

Question 1
There are 5 letters (B, O, K, E, R) and there is a total of 10 letters to make up the word.
There are

ways of arranging the letters, which equal to 210 ways
Question 2
