In the equation y = 5 ln(x), what is the value of c? The answer, in this particular case, is that c equals 1. – – – The equation y = a ln(x) is the standard form of the equation for an exponential function. The value of c in this case, which we refer to as “the curvature,” can be found by taking the natural logarithm (ln) and then raising it to power. In other words: lng(y)=c or logg(a)(lnb)=c where g=power and b=base number. So what does that mean? It means that when x becomes equal to zero, or equivalently, when x approaches infinity (as far as your graphing calculator is concerned), the curve’s maximum point will occur at approximately five units on its axis. logg(a)(lnb)=c where g=power and b=base number. So what does that mean? It means that when x approaches infinity (as far as your graphing calculator is concerned), the curve’s maximum point will occur at approximately five units on its axis.”}]}} ]}} }}{{lang=”
