A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions.
The function f of x is defined as f of x is equal to 49 minus x squared. Find the value of f of 5. So whenever you're dealing with a function, you take your input. In this case, our input is going to be our 5. We input it into our little function box, and we need to get our output.
To evaluate a function is to: Replace ( substitute) any variable with its given number or expression. Like in this example: Example: evaluate the function f (x) = 2x+4 for x=5. Just replace the variable "x" with "5": f ( 5) = 2× 5 + 4 = 14. Answer: f (5) = 14.
