Q. f(x)=12ex and f(4)=16+12e4.f(0)= \begin{array}{l}f^{\prime}(x)=12 e^{x} \text { and } f(4)=-16+12 e^{4} . \\ f(0)=\end{array}
  1. Integrate f(x)f'(x): To find the value of f(x)f(x) at x=0x = 0, we need to integrate the derivative f(x)f'(x) to get f(x)f(x). The derivative f(x)=12exf'(x) = 12e^x is given.\newlineIntegration of f(x)f'(x) will give us f(x)=12ex+Cf(x) = 12e^x + C, where CC is the constant of integration.
  2. Find Constant of Integration: We are given the value of the function at x=4x = 4, which is f(4)=16+12e4f(4) = -16 + 12e^4. We can use this information to find the constant of integration CC. Let's substitute x=4x = 4 into the integrated function f(x)=12ex+Cf(x) = 12e^x + C. 12e4+C=16+12e412e^4 + C = -16 + 12e^4
  3. Calculate Complete Function: Solving for CC, we subtract 12e412e^4 from both sides of the equation:\newlineC=16+12e412e4C = -16 + 12e^4 - 12e^4\newlineC=16C = -16
  4. Substitute x=0x = 0: Now that we have the constant of integration, we can write the complete function f(x)f(x):f(x)=12ex16f(x) = 12e^x - 16
  5. Simplify Expression: To find f(0)f(0), we substitute x=0x = 0 into the function f(x)f(x):f(0)=12e016f(0) = 12e^{0} - 16
  6. Simplify Expression: To find f(0)f(0), we substitute x=0x = 0 into the function f(x)f(x):
    f(0)=12e016f(0) = 12e^0 - 16Since e0e^0 is equal to 11, we can simplify the expression:
    f(0)=12(1)16f(0) = 12(1) - 16
    f(0)=1216f(0) = 12 - 16
    f(0)=4f(0) = -4
