Question

The graph of f(x) = −x2 − 2x + 8 is shown. Which of the following describes all solutions for f(x)?

Answer 1

Explanation:

The solutions of a quadrtic equation is gthe point where

$f(x)=0$

The quadratic equation is given below as

$f(x)=-x^2-2x+8$

Hence,

The solution from the graph are the points where the curve cuts the x-axis

All solutions of the curve also indicates the domain of the funtion

The domain of the function is given below as

[tex]\begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:

Hence,

The final answer is

The FIRST OPTION is the correct answer
