- The hyperbolic cosine function, denoted cosh x, is used to model the shape of a hanging cable (a telephone wire, for example). It is defined as cosh x = e^x + e^-x / 2. a. Determine its end behavior by evlauating the limit of cosh x from x from positive inifinity and the limit of cosh x from x from negative inifnity. b. Evaluate cosh 0. cosh 0 = Use symmetry and part (a) to sketch a plausible graph for y = cosh x.Find a point c satisfying the Mean Value Theorem for y=sqrtx on the interval [9,25]What is the limit as x goes to infinity of (ln(x3 + 9) - ln(2x3 + 17x))?
