it can be used because f(x)=4x^2 + x + 3 is continuous on -1,1 and the function is defined at x=-1 and x = 1. b. there is/are a solution(s) to the equation in (-1,1) at x≈□. (type an integer or decimal rounded to three decimal places as needed. use a comma to separate answers as needed.)
Answer
Answer:
We need more information to find the value of (x). For example, we need to know what the equation is that (f(x)=4x^{2}+x + 3) is related to. Without that, we cannot provide a numerical answer.
Explanation:
Step1: Analyze given function
Given (f(x)=4x^{2}+x + 3) continuous on ([-1,1]).
Step2: Identify missing info
No equation to solve for (x) is provided.
