What is the derivative of f(x) = 3x^2 + 2x - 1 using the Power Rule?
6x + 2
What is the purpose of simplifying a derivative?
Easier analysis
How do you verify the derivative of f(x) = 3x^2 + 2x - 1 if the derivative is f'(x) = 6x + 2?
Substitute into f'(x)
A polynomial function is defined as the sum of terms with constant coefficients and positive integer exponents. For example, `f(x) = 3x^2 + 2x - 1` requires the Power Rule.
A logarithmic function involves a logarithm with any base, such as `k(x) = log(x)`, which requires the Logarithmic derivative rules.
Inverse functions, such as `q(x) = arcsin(x)`, require the inverse function derivative formula.
If `y` is defined indirectly through an equation with `x`, such as `x^2 + y^2 = 1`, the appropriate technique is Implicit Differentiation.
Trigonometric functions involve sine, cosine, tangent, or their reciprocals, and require standard trigonometric derivative rules.
Match the function type with its differentiation technique:
Polynomial ↔️ Power Rule
Trigonometric ↔️ Trigonometric Derivative Rules
Exponential ↔️ Exponential Derivative Rules
Composite ↔️ Chain Rule
Implicit ↔️ Implicit Differentiation
To differentiate the inverse of a function, use the inverse function derivative formula
