Homework Statement
evaluate f(x+h) expand and simplfy f(x)=x^3-7x^2+x+1?
Homework Equations
f(x+h)
The Attempt at a Solution
my attempt (f(x+h)+f(x)+1
x^2(x+h)+x+1
x^2(x+7)+x1
im lost I'm not sure how to do this
LCKurtz said:Replace the x's with x+h and simplify.
psp101 said:o really so is it like
f(x)=(x+h)^3-7(x+h)^2+(x+h)+1
then I simplify
J-Girl said:yeah but the original equation is usually set up at(when u are evaluating the limit) (x+h)-f(x), so you have to minus the original function from the (x+h)^3-7(x+h)^2+(x+h)+1, you will just end up with the first derivative.
"Function" refers to a block of code that is designed to perform a specific task. It can take in inputs, perform operations, and return a result.
The function you need to use depends on the specific task you are trying to accomplish. You can refer to the documentation for the programming language you are using or do a quick internet search for functions that perform the specific task you need.
A built-in function is a pre-defined function that is already available in the programming language you are using. A user-defined function is created by the programmer to perform a specific task that is not already built into the language.
To call a function, you need to use its name followed by parentheses that may contain any necessary arguments. For example, if you have a function called "add" that takes in two numbers, you would call it like this: add(3, 5).
Yes, a function can call another function. This is known as function composition, where the output of one function becomes the input for another function. This allows for more complex tasks to be broken down into smaller, more manageable functions.
