If you're talking about the soccerball to football one, it would be a
Answer:
y = 1.5x + 1.5
Step-by-step explanation:
First, plot 2x + 3y = 15 on a graph. Then plot (1,3) on a graph. After that, draw a line that passes through (1,3) and forms 90 degrees angles with 2x + 3y = 15. Then find the equation of that line by finding the y-intercept (0, 1.5). Then head up to the intersection point (1.6153846153846, 3.9230769230769). Subtract 1.5 from y. (2.4230769230769) Then divide by 1.5 (1.6153846153846). Reverse the operations you just did (in reverse order) to get the equation y = 1.5x + 1.5.
(I don't know how to explain this too well. Here's a graph to make more sense of it.)
If

then by the product rule,

and by the chain rule,

which leaves us with

Alternatively, if you exclusively want to use the chain rule, you can carry out logarithmic differentiation:

By the chain rule, differentiating both sides with respect to <em>x</em> gives

Solve for <em>f'(x)</em> yields
