Hi can someone help me with this

A function f is given by the table shown

estimate f'(4.3)

x......3.7...4.3...4.9...5.5...6.1
f(x)..1.8...3.4...4.6...6.4...8.4

a)0.500
b)2.333
c)2.000


How am I supposed to do this?

Thanks
 
you estimate the slope of a tangent line with the slope of a secant line.

a good estimate would be the secant line w/ endpoints symmetrical to the point of interest

\(\displaystyle \L f'(4.3) \approx \frac{f(4.9) - f(3.7)}{4.9 - 3.7}\)
