Find y" in Exercises 71-78 1 X 71. y = 1 + 3

Find the second derivative of each function. Do not leave negative exponents in answers: (a) y = [5x^1/2] - [2x^-1] (b) y = (x+2)([x^2] - 4) + [e^3x]

say that h'(x)=(x^2-6x-7)/(x-6). Make a sign chart for the first derivative of h(x).

We can use the product rule to find the first derivative, y', since function y is the product of two functions, 02 and 90 + 3. However, expanding their product first will simplify the process for finding the higher derivatives of y. y = 02(90 + 3) = 903 +
