| 0% | Verify the derivative of $$f(x)=x^2$$ using the limit definition by ranking the steps. Order the steps from first to last:
A: Write the difference quotient as $$\frac{(a+h)^2 - a^2}{h}$$
B: Expand $$(a+h)^2$$ to obtain $$a^2 + 2*a*h + h^2$$
C: Cancel the $$a^2$$ terms and factor h from the numerator
D: Take the limit as $$h \to 0$$ to conclude that the derivative is $$2*a$$ AP Calculus AB / Unit 2: Differentiation: Definition and Fundamental Properties | 0/1 | April 14, 2026 20:11 |
