To solve: The given inequality using sign chart.
The solution set is equal to
Given information:
Consider the given inequality.
Calculation:
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 are
Now, locate these boundary points on the number line (or sign chart) and dividing the number line into intervals and check the function
The boundary points divide the number line into three test intervals. Including the boundary points (because of the given greater than or equal to sign), the intervals are below:
Now, take one representative number within each test interval and substitute that number into the inequality below:
Therefore, the intervals
The combined intervals are below:
Hence, the solution set is
