How to find integrals of parent functions without any horizontal/vertical shift?

In summary, the conversation discusses how to find integrals of parent functions without any horizontal or vertical shift. It is mentioned that this can be done using a calculator that can only add, subtract, multiply, and divide. There is also a general formula for finding the integral of a function of the form Cxp where p ≠ -1. The conversation also addresses the difficulty of computing accurate approximations for 9^{1/7} and 14^{8/7} using a limited calculator. One suggested approach is to use polynomial expansion or iteration to find corrections.

You have a function of the form Cxp where p ≠ -1.
The integral is Cxp+1/(p+1)

The difficulty here is to compute (adequate approximations to) [itex]9^{1/7}[/itex] and [itex]14^{8/7} = 14 \cdot 14^{1/7}[/itex] using "a calculator that can only add, subtract, multiply, divide".

1261/7≈1281/7=2
One could then do the polynomial expansion (2-x)7=126 and throw away higher terms to find corrections. Or do some iteration.
 

1. What are parent functions?

Parent functions are basic, unaltered functions that serve as the building blocks for more complex functions. They are typically the simplest form of a specific type of function, such as linear, quadratic, or exponential.

2. How do I find the integral of a parent function?

To find the integral of a parent function, you can use basic integration rules and techniques, such as the power rule, substitution, or integration by parts. It is important to first identify the type of function and then apply the appropriate integration method.

3. What is a horizontal/vertical shift?

A horizontal shift is a transformation of a function that moves it left or right along the x-axis. A vertical shift, on the other hand, moves the function up or down along the y-axis. These shifts can affect the shape and position of the function, making it necessary to adjust the integration process accordingly.

4. How do I handle a horizontal/vertical shift when finding the integral?

If the parent function has a horizontal or vertical shift, you can use the properties of integration to adjust the integral accordingly. For horizontal shifts, you can use the formula ∫f(x-c)dx = ∫f(x)dx + C, where c is the amount of the shift. For vertical shifts, you can simply add or subtract the amount of the shift to the integral's result.

5. Are there any shortcuts for finding integrals of parent functions without shifts?

Yes, there are certain parent functions that have well-known integrals that can be used as shortcuts. For example, the integral of a linear function is simply the area of the corresponding rectangle, and the integral of a quadratic function can be found using the power rule. However, it is important to understand the general integration process for parent functions in order to apply these shortcuts correctly.
