question 19 (1 point) find the limit algebraically. lim x x→4 a 0 b 1 c -4 d 4

Explanation:

Step1: Recall limit - value rule

For the function (y = x), when finding (\lim_{x\rightarrow a}x), we can directly substitute the value (a) into the function.

Step2: Substitute (x = 4)

Here (a = 4), so (\lim_{x\rightarrow4}x=4).

Answer:

D. 4
