derivative: . If we set this equal to zero, there is also no solution.Therefore, there are no maxima, minima, or points of inflection. Note that the first derivative isalways positive. This means that the curve is always increasing. Also notice that the secondderivative changes sign from positive to negative at x = −8. This means that the curve isconcave up for values of x less than x = −8 and concave down for values of x greater than x =−8.Now, we can draw the curve. It looks like the following:
