Find the equation of the tangent line to the curve at the given point. Illustrate by graphing the curve and the
tangent line on the same screen.
y = 6x - 5/x, (1, 1)
Step 1
We can find the equation of a line by using the Point-Slope formula y - Yo = m(x - xo). This means that we
need to find the slope m of the line and a point (xo, Yo) on the line.
We begin by finding the slope. The line tangent to f(x) at (xo, Yo) will have the slope m = f '(xo). We have
y = f(x) = 6x – 5/x. Since 5Vx = 5x1/2, then
-1/2
f '(x) = 6
Step 2
Using f '(x) = 6 -
we can now find the slope of the tangent line at (1, 1) by finding the following.
m = f
1
-1/2
= 6 -
