Kojo wants to be an author. to improve his writing skills, every day after school he writes 33 pages of a story he is working on. kojo has been writing his story for dd days. he has a total of 81 pages completed. write an equation to describe this situation.

Step-by-step explanation:

Given : Kojo wants to be an author. To improve his writing skills, every day after school he writes 3 pages of a story he is working on.

Kojo has been writing his story for d days.

Then, the total number of pages he wrote = 3d

If  has a total of 81 pages completed, then the equation describe this situation will be :-

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
