Answer:
This is frankly impossible.
Step-by-step explanation:
What you have given me are three x-intercepts. And it is impossible for a quadratic function to have more than two roots. However, if this was an cubic function, we could multiply (x+5)(x-1)(x-4) which results in the equation which simplifies into x^3 -21x + 20. However, this is a cubic function, not a quadratic function, so something must be wrong with this problem all together.
Answer:

-----
7/4
Multiply the top and bottom by 4/7
7*4/7
-----
7/4 *4/7
4
-----
1
He can write 4 pages per hour
F(1) = 6
f(2) = 6 - 5 = 1 => f(2) = f(1) - 5
Required recursive formular => f(n + 1) = f(n) - 5
