Identify Limit Form: Identify the form of the limit as x approaches 4. We substitute x with 4 in the expression −3x+32x+1 to see if the limit can be directly calculated. −3⋅4+32⋅4+1=−12+38+1=−99=−1. Since we get a determinate form (not 0/0 or ∞/∞), we can conclude that the limit is −1.
Substitute x with 4: Conclude the limit based on the calculation from Step 1.Since we obtained a numerical value in Step 1, we can conclude that the limit of (2x+1)/(−3x+3) as x approaches 4 is −1.
