The Challenge:
Find the derivative of $f(x) = 3x^4 - 5x^2 + 2x - 7$
Step 1: Apply Power Rule $\frac{d}{dx}[x^n] = nx^{n-1}$
$f'(x) = (3 \cdot 4)x^3 - (5 \cdot 2)x^1 + (2 \cdot 1)x^0 - 0$
Final Result: $f'(x) = 12x^3 - 10x + 2$
The Challenge:
Solve $\frac{dy}{dx} = 3y$ where $y(0) = 5$
1. Separate variables: $\int \frac{1}{y} \, dy = \int 3 \, dx$
2. Integrate: $\ln|y| = 3x + C$
3. Solve for y: $y = Ae^{3x}$ where $A = e^C$
General Solution: $y = 5e^{3x}$
