Final answer:
To determine the infinite limit, we evaluate the expression as x approaches -9 from the left. In step 1, the numerator approaches -9.
Step-by-step explanation:
To determine the infinite limit of x as it approaches -9 from the left, we need to evaluate the expression x * 10x - 9.
Step 1: As x approaches -9 from the left, the numerator (x) approaches -9 because we are approaching from the left side. This means that x = -9.
