+129899 First one
Rate of change from 5 to 9 = f(9) - f(5) 14 - (-2) 16
_________ = ________ = ___ = 4
9 - 5 4 4
Second one
( f/g)(x) means f(x) 4x^2 + 6x 2x ( 2x + 3) 2x
____ = ______________ = _____________ = _____
g(x) 2x^2 + 13x + 15 (2x + 3) (2x +5) 2x + 5
Last one
x x^2 - 6x + 8 x - 2
0 8 -2
1 3 -1
2 0 0
3 -1 1
4 0 2
5 3 3
The solutions occur at x = 2 and x = 5
