Question: top-left: Consider the function $F$ such that $F'(x) = 4e^x$. If $F(-3) = 10$, determine $F(2)$. bottom-right: (5 Marks)
1. **State the problem:** We are given the derivative of a function $F$, which is $F'(x) = 4e^x$, and a value of the function at $x = -3$, $F(-3) = 10$. We need to find the value of $F(2)$. 2. **Recall the formula:** Since $F'(x)$ is the derivative of $F(x)$, we can find $F(x)$ by integrating $F'(x)$: $$F(x) = \int F'(x) \, dx + C$$ where $C$ is the constant of integration. 3. **Integrate $F'(x)$:** $$F(x) = \int 4e^x \, dx + C = 4 \int e^x \, dx + C = 4e^x + C$$ 4. **Use the initial condition $F(-3) = 10$ to find $C$:** $$10 = F(-3) = 4e^{-3} + C$$ Solve for $C$: $$C = 10 - 4e^{-3}$$ 5. **Write the full function:** $$F(x) = 4e^x + 10 - 4e^{-3}$$ 6. **Find $F(2)$:** $$F(2) = 4e^2 + 10 - 4e^{-3}$$ This is the exact value of $F(2)$. **Final answer:** $$\boxed{F(2) = 4e^2 + 10 - 4e^{-3}}$$
