The following function is graphed below:
For which values of x is
f(x)>0 true?
The following function is graphed below:
For which values of x is
f(x)>0 true?
The given function is .
First, we find the roots of the equation , which are the critical points where the function can change its sign.
Using the quadratic formula , where , , and :
Calculate the discriminant .
The discriminant is negative, indicating there are no real roots.
Because the parabola opens downwards and there are no x-intercepts (real roots), the function does not cross the x-axis.
Hence, for all real numbers, .
Therefore, there are no values of for which .
Thus, the solution is: No answer.
No answer
