Homework Help: calculus

Posted by maura on Friday, September 14, 2012 at 3:24pm.

To find the equation of a line, we need the slope of the line and a point on the line.

Since we are requested to find the equation of the tangent line at the point (64, 8), we know that (64, 8) is a point on the line. So we just need to find its slope.

The slope of a tangent line to f(x) at x = a can be found using the formula
mtan = lim x→a f(x) − f(a)/x − a

In this situation, the function is
f(x) = a=
