Suppose
f = f(x) satisfies f(9) = f(9.01) = 3.Estimate the value of df/dx at x = 9.
Can you explain how you got this answer? I'm super confused. We had done one in class that was easier because it was worded slightly different and I could just do y2-y1 over x2-x1.
ex. f(2)=5 and f(2.005)=5.012. well you would just subtract 5.012-5 over 2.005-2 which gives you 2.4.
The problem I posted I was stuck staring at versus the one above.
