Find the limit using direct substitution.lim x→23 x − 7 − 3x
Question
Find the limit using direct substitution.lim x→23 x − 7 − 3x
Solution
To find the limit of the function as x approaches 23 using direct substitution, you simply substitute 23 in place of x in the function.
The function is: x - 7 - 3x
Substitute x = 23:
= 23 - 7 - 3*23 = 23 - 7 - 69 = -53
So, the limit of the function as x approaches 23 is -53.
