X² - 5x - 14 = (x - 7)(x + 2)
<span>This exercise should show you that as h approaches zero
you get the value of the derivative of x^2 at x=1.
</span><span>the change in x^2) / h
h=1___
h=.1____
h=0.1_____
h=.001___
</span>
<span>change in x^2 = (1+h)^2 - 1^2 = (1+h)^2 - 1</span>
The first one, the y intercept is -3
