To find: The graph of the given function changes sign at
The answer is true.
Given information:
Consider the given function.
Calculation:
First find the boundary points of the function
To set numerator and the denominator equal to zero. These are the values that make the quotient zero or undefined and solve for
And
So, the boundary points of the function
Now, locate these zeros on the number line (or sign chart) and dividing the number line into intervals and check the function
Therefore, the sign changes of the function
Hence, the answer is true.
