Instead of using the quotient rule, you can first expand <em>y</em> :
<em>y</em> = (4<em>x</em> - 1)^2 / <em>x</em> ^2 = (16<em>x</em> ^2 - 8<em>x</em> + 1) / <em>x</em> ^2 = 16 - 8/<em>x</em> + 1/<em>x</em> ^2
Then the derivative is
d<em>y</em>/d<em>x</em> = -8/<em>x</em> ^2 - 2/<em>x</em> ^3
The tangent to the curve at (-1, 25) then has a slope or gradient of
d<em>y</em>/d<em>x</em> = -8/(-1)^2 - 2/(-1)^3 = -6

<h3>What is a scale drawing? </h3>
A scale drawing is a smaller image in terms of dimensions of a bigger image / building / object.
The scale of the drawing = original dimensions / dimensions of the scale drawing
<h3>What is the value of k? </h3>
The value of k = height of the antenna / length of the antenna in the model
750 / 1..02 = 735 feet
