Limit Calculations
-
Task involves finding limits for given functions
-
Example function for limits:
- ( f(x) = \begin{cases} x^3 & \text{if } x < 1 \ x^2 & \text{if } x \geq 1 \end{cases} )
- Compute:
- ( \lim_{x \to -1} f(x) )
- ( \lim_{x \to 1} f(x) )
-
Additional limits to evaluate:
- ( \lim_{t \to 2} \frac{t^2 - 4t + 4}{t - 2} )
- ( \lim_{t \to 0} \frac{t^2 - 4t + 4}{t - 2} )
Derivative Calculations
- Derivatives must be calculated using the definition of a derivative, not relying on common derivative tables
- Functions to find derivatives for:
- ( y(x) = 7x^2 )
- ( y(x) = 2x - 10 )
- ( y(x) = x )
Function Slope Inquiry
- The slope of the function ( y(x) ) is given as 10
- Explanation required discussing implications for the behavior of the function
Derivative Existence Analysis
- Analyze a piecewise function:
- ( y(x) = \begin{cases} \cos(x) & \text{if } x \geq 0 \ -2x + 1 & \text{if } x < 0 \end{cases} )
- Objective:
- Determine if there are points where the derivative does not exist
- Justification should be based on logical reasoning rather than graph analysis
