Question

Which function should be used to when evaluating the function at x = 4? HELP PLEASE!!

Answer 1

The function to be used for when evaluating the function at x = 4 is p(x) = 1/4x + 2.5. Option B

First, we need to know that functions are described as fundamental mathematical entities that describe relationships between a set of inputs (often called the domain) and a set of outputs (often called the range).

A function assigns exactly one output value to each input value. It's like a machine that takes an input, performs a specific operation, and produces an output.

For the function, p(x) = 1/4x + 2.5 if for when x >3

Now, we can see that numbers greater than 3 are from 4, 5, 6, 7...

Thus, this function meets the criterion for evaluating the function at x = 4

Answer 2

The answer to your question is p(x) = (1/4)x + 2.5

Explanation:

To solve this question we must observe the conditions of each function.

-We must use the first function only if the value of x is equal to or lower than 3.

-We must use the second function only of the value of x is higher than 3.

For the value given (4), we notice that it is higher than 3 so we must use the second function.
