Identifying Values of X for Which 5x² < 0: A Quadratic Inquiry

Question

Given the function:

y=5x2 y=5x^2

Determine for which values of x f\left(x\right) < 0 holds

Step-by-Step Solution

To solve this problem, consider the nature of the quadratic function y=5x2 y = 5x^2 . The function has a leading coefficient of 5, which is positive, indicating that the parabola opens upwards.

A parabola opening upwards, such as this one, has its minimum value at the vertex. For the function y=5x2 y = 5x^2 , the minimum value occurs at x=0 x = 0 , where y=502=0 y = 5 \cdot 0^2 = 0 . Since y=5x2 y = 5x^2 is a non-negative quadratic for all real x x , the function f(x)=5x20 f(x) = 5x^2 \geq 0 for all x x .

This means that there are no values of x x for which f(x)<0 f(x) < 0 holds. The function is only zero when x=0 x = 0 and positive otherwise for any non-zero x x .

Conclusively, there are no values of x x where f(x)<0 f(x) < 0 . Therefore, the solution is that no x x satisfies f(x)<0 f(x) < 0 .

Hence, the answer is that there are

No x.
