Graph the function \( f(x)=x+4 / x \) Graph the secant line that passes through the points \( (1,5) \) and \( (8,8.5) \) on the same set of axes Find the number \( c \) that satisfies the conclusion of the Mean Value Theorem for \( f \) on \( [1,8] \) \( c= \) Notice that if you graph the tangent line to the point \( (\mathrm{c}, \mathrm{f}(\mathrm{c})) \) it is parallel to the secant line.
