lim Δx→0 5x + Δx − 5xΔx
Solution
The given expression is: lim Δx→0 (5x + Δx - 5x)/Δx
Step 1: Simplify the expression inside the limit. The 5x terms cancel out, leaving us with:
lim Δx→0 Δx/Δx
Step 2: The Δx terms cancel out, leaving us with:
lim Δx→0 1
Step 3: The limit of a constant as Δx approaches any value is just the constant itself. So, the answer is:
