Find First Derivative: To find the second derivative of y with respect to x, we first need to find the first derivative. The function y=3x is an exponential function, and the derivative of an exponential function with base a (where a is a constant) and exponent x is given by the formula dxdy=ax⋅ln(a). In this case, a=3, so we apply this formula to find the first derivative.Calculation: dxdy=3x⋅ln(3)
Differentiate Again: Now that we have the first derivative, we need to differentiate it once more to find the second derivative. We apply the same rule for differentiation of an exponential function.Calculation: dx2d2y=dxd(3x⋅ln(3))=ln(3)⋅dxd(3x)Since ln(3) is a constant, it remains unchanged during differentiation. The derivative of 3x with respect to x is again 3x⋅ln(3).
Combine to Find Second Derivative: Combining the constant ln(3) with the derivative of 3x, we get the second derivative.Calculation: dx2d2y=ln(3)×(3x×ln(3))=(ln(3))2×3x
