Given that f(x) = x2 –3x – 40 and g(x) = x +5, find (f +g)(x) and express the result in standard form.

Step-by-step explanation:

So we have the two functions:

And we want to find (f+g)(x). This is the same as:

Substitute:

Combine like terms:

Add:

And we're done!

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
