Question

Find the limit as x approaches 2 of x² - 2x - 7 = 1.

a) -3
b) 0
c) 1
d) 3

Answer 1

To find the limit of x² - 2x - 7 as x approaches 2, you substitute x with 2 and simplify. The computation 4 - 4 - 7 yields the answer -3.

Step-by-step explanation:

The question asks to find the limit as x approaches 2 of the function x² - 2x - 7, and it is mistakenly equated to 1 in the question, but we will ignore that part as instructed. To find the limit, we will simply substitute x with 2.

• x² - 2x - 7

• (2)² - 2(2) - 7

• 4 - 4 - 7

• -3

Therefore, the limit as x approaches 2 of x² - 2x - 7 is -3.
