lim(x-1)(2x+3)

x-->3

To find the limit of a function as x approaches a specific value, we can simply substitute that value into the function.

In this case, we want to find the limit of the function (x-1)(2x+3) as x approaches 3. So we substitute x = 3 into the function.

Replacing x with 3, we get:
(3-1)(2(3)+3) = (2)(6+3) = (2)(9) = 18

Therefore, the limit of the function (x-1)(2x+3) as x approaches 3 is equal to 18.
