Answer: 
Step-by-step explanation:
There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form
for some constant a.
To find a, we can substitute the coordinates of the y-intercept, (0, -50).

So, 
Let's call the number you thought of n. Then what the two steps you took can be written as an equation:

Subtract n to get all of your variables to one side:

At this point, I recommend turning your mixed number into an improper fraction. It will make things easier later on:

Now divide both sides by 11 to get the value of n:

Answer:
there is no y intercept. if there was it would be at the end of -3x
Answer:
b=5..............is the answer
