Question

Does anyone know the answer to this? I can't understand why it isn't -7.​

Answer 1

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

How to calculate the value?

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7
