The point P(16,8) lies on the curve y=√(x)+4

Let Q be the point (x,√x+4).

A.) Find the slope of the secant line PQ for the following values of x. (Answers should be correct to at least 6 decimal places.)

If x=16.1, the slope of PQ is:
and if x=16.01, the slope of PQ is:
and if x=15.9, the slope of PQ is:
and if x=15.99, the slope of PQ is:

B.) Based on the above results, guess the slope of the tangent line to the curve at P(16,8).

Step 1

The points P= (16,8) and Q= (x, x^1/2+4) lies on the curve which is given by:

Step 2

If the secant line is passing through the points P = (x1, y1) and Q = (x2, y2) then the slope of the secant PQ is given by:

Step 3

Now, at x=16.1 the point Q is (16.1,8.01). then the slope of secant l...
