I cant see your work very clearly so I'll work it out below:-
f(x + Δx) = (x + Δx)^2 - 2(x + Δx) - 3
= x^2 + 2x(Δx) + (Δx)^2 - 2x - 2(Δx) - 3
= x^2 - 2x + (Δx)^2 + 2x(Δx) - 2(Δx) - 3
Answer:
80,60
Step-by-step explanation:
If you meant to write
then the statement is true.
As a more concrete example, something like
would be read out as "log base 3 of 81 is equal to 4".
5, 3, -3, -7, -9
This is in descending order.
