Let f(x) = x^(1/3). The equation of the tangent line to f(x) at x = 8 can be written in the form y = mx+b where m is: and where b is:
Using this, we find our approximation for 8.1^(1.3) is:
I found the slope to be 1/12
I found b to be 1.3333333333333333333
I still can't get the answer for the approximation for 8.1^(1/3).
I plugged it correctly in the mx+b equation but it won't work.
Is there another way to do this? Please help.
