I would just like to make sure I'm doing this right..thanks
let f(x)=x^2 x=-2, and x=1.9
f(-1.9)^2=-3.61
f(-2)^2=-4
(-3.61)-(-4)
(-1.9)-(-4)
=.39
2.1
=0.185714285

let f(x)=x^2 x=-2, and x=1.9 --------------------------> [is it x = 1.9 or x = -1.9 ? ]
f(-1.9)^2=-3.61
f(-2)^2=-4
(-3.61)-(-4)
(-1.9)-(-4)
=.39
2.1
=0.185714285
Is it x = 1.9 or x = -1.9 ?
I assume that it is x = -1.9
