Look at the following function:
Determine for which values of the following is true:
To solve this problem, we need to rewrite the quadratic function into its vertex form. This process allows us to find the vertex and understand the behavior of the function.
First, we complete the square for the quadratic expression. Starting with:
We take the -terms and complete the square as follows:
Therefore, can be rewritten as:
Now, the function is in the form , which shows the vertex at . The vertex is the minimum point because the parabola opens upwards (as the coefficient of is positive).
This vertex indicates that the minimum value of is 1, which means the function never reaches below zero. As a result, the function never assumes negative values.
Based on this analysis, we conclude that the function has no negative values.
The correct answer is therefore: The function has no negative values.
The function has no negative values.
The graph of the function below does not intersect the \( x \)-axis.
The parabola's vertex is marked A.
Find all values of \( x \) where
\( f\left(x\right) > 0 \).
This quadratic doesn't factor nicely over real numbers! The discriminant is negative, meaning no real roots exist.
Look at the coefficient of ! Since it's positive (+1), the parabola opens upward like a smile. This means the vertex is the minimum point.
It means the function has no solutions. The smallest value this function can take is 1 (at the vertex), which is always positive.
Yes! For , the discriminant is . A negative discriminant confirms no real solutions exist.
