You can put this solution on YOUR website! 0. given f(x) =8x -2 and g(x) = 2x -3 find f-g
1. given f(x) =5x + 4 and g (x) =3x-8 find f.g
2. given f(x) +2 -2x and g(x) = -6 +2, find f+g
3. find the distance between the pair of points (-1,-4) and (-5,-7)
s^2 = diffy^2 + diffx^2
s^2 = (-4+7)^2 = (-1+5)^2
s^2 = 9 + 16 = 25
s = 5

4. find the distance between the pair of points (-2,-6) and (7, -3)
Do it like #3 above.
----------------------
5. find the midpoint of the line segment with the given and points (2,1) and (6,8)
Get the averages of x any y separately.
for x: (2+6)/2 = 4
for y: (1+8)/2 = 9/2
Midpoint is (4,9/2)

6. find the center and radius of a circle given the following equation of the circle x^2 + y^2 = 100
A circle of radius r about center (h,k) is:
(x-h)^2 + (y-k)^2 = r^2
This one is centered about the Origin (0,0) with a radius of 10 (sqrt(100)).
-----------------
7. given f(x) = -3x + 2 and g(x) = 2x +9, find (gof)(x)
8. given f(x) = 5x +7 and g(x) = 5x -1 find (fog)(x)
9. write the standard form of the equation of the circle with the given center(-2, -4) and the radius 6.
