Question

Graph y = √x on a sheet of paper.  Label the points x = 4 and x = 16 on the x –axis.  Find the corresponding point on the curvy y = √x at x = 4 (Call this Point P4) and x = 16 (Call this Point P16).  Draw the tangent lines at P4 and P16. Compare the tangent lines you constructed.

  a.

The slope of the tangent at x = 4 is less than the slope of the tangent at x = 16

  b.

The slope of the tangent at x = 4 is greater than the slope of the tangent at x = 16

  c.

The slope of the tangent at x = 4 is equal to the slope of the tangent at x = 16

  d.

The slope of the tangent at x = 4 exist but the slope of the tangent at x = 16 does not exist.

  e.

None of these

Step 1

When x=4 then y=sqrt(4)=2

So point is (4,2)

Step 2

When x=16 then y=sqrt(16)=4

So, point is (16,4)
