Q. Find the instantaneous rate of change of f(x)=xf(x) = x at x=−13x = -13.\newlineWrite your answer as an integer or a fraction. Simplify any fractions.\newline____\newline
  1. Identify Total Tape Amount: Identify the total amount of electrical tape needed and the amount per roll.\newlineTotal tape needed = 8,000 cm8,000\,\text{cm}, Tape per roll = 2,000 cm2,000\,\text{cm}.
  2. Calculate Rolls Required: Calculate the number of rolls required by dividing the total tape needed by the tape per roll. 8,000 cm÷2,000 cm=48,000 \, \text{cm} \div 2,000 \, \text{cm} = 4 rolls.
