Solve (4x+22)² < 0: Finding Values for Negative Quadratic Output

Question

Look at the function below:

y=(4x+22)2 y=\left(4x+22\right)^2

Then determine for which values of x x the following is true:

f(x) < 0

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Analyze the given function.
  • Step 2: Determine the nature of (4x+22)2 (4x + 22)^2 .
  • Step 3: Conclude whether it can ever be negative.

Step 1: We are given the function y=(4x+22)2 y = (4x + 22)^2 . This is a quadratic function expressed as a square of a linear term.

Step 2: Consider the expression (4x+22) (4x + 22) . Whatever value this linear expression takes, its square, (4x+22)2 (4x + 22)^2 , will always be non-negative. This is because the square of a real number is never negative.

Step 3: To find when (4x+22)2<0 (4x + 22)^2 < 0 , we realize that since squares are non-negative, they cannot actually be negative. Thus, (4x+22)20 (4x + 22)^2 \geq 0 for all values of x x , and can never be less than zero.

Therefore, no value of x x will make f(x)<0 f(x) < 0 .

The conclusion is that there is no value of x x for which f(x)<0 f(x) < 0 .

Answer

No value of x x
