Given the function:
Determine for which values of x holds
To solve this problem, consider the nature of the quadratic function . 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 , the minimum value occurs at , where . Since is a non-negative quadratic for all real , the function for all .
This means that there are no values of for which holds. The function is only zero when and positive otherwise for any non-zero .
Conclusively, there are no values of where . Therefore, the solution is that no satisfies .
Hence, the answer is that there are
No x.The graph of the function below intersects the X-axis at points A and B.
The vertex of the parabola is marked at point C.
Find all values of \( x \) where \( f\left(x\right) > 0 \).
Because any number squared is positive or zero! Whether x is positive or negative, . Since we multiply by positive 5, the result always.
Then the function would always be ≤ 0! A negative coefficient flips the sign, so for all x ≠ 0.
Look at the range of the function. If you need f(x) < 0 but the function is always ≥ 0, then there are no solutions. Graph it or test values to confirm!
Yes! When we say "No x" or "No solution", mathematically this means the empty set ∅. There are simply no values that satisfy the condition.
For : No solutions
For : Only x = 0 works
The equals sign makes all the difference!
