q4\n1 point\ncompute the derivative of $f(x)$ algebraically.\n$f(x)=x^2 - 2$\n$\bigcirc$ $f(x)=2$\n$\bigcirc$ $f(x)=2x - 2$\n$\bigcirc$ $f(x)=2x^2$\n$\bigcirc$ $f(x)=2x$
Answer
Explanation:
Step1: Differentiate $x^2$ term
Using power rule: $\frac{d}{dx}(x^n)=nx^{n-1}$, so $\frac{d}{dx}(x^2)=2x^{2-1}=2x$
Step2: Differentiate constant term
Derivative of constant $c$ is 0: $\frac{d}{dx}(-2)=0$
Step3: Combine results
Add derivatives of individual terms: $f'(x)=2x + 0$
Answer:
$f'(x)=2x$ (matches the option: $f'(x)=2x$)
