Q. Find the linearization of f(x)=x2−4x+5f(x) = x^2 - 4x + 5 at x=3x = 3. Write an exact answer.\newlineL(x)=L(x) = ______
  1. Identify Total Tape Needed: Identify the total amount of 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}.\newlineWe need to divide the total tape needed by the tape per roll to find the number of rolls.\newlineCalculation: 8,000÷2,000=48,000 \div 2,000 = 4.
  2. Calculate Number of Rolls: Confirm the calculation.\newlineRecheck: 8,0008,000 divided by 2,0002,000 still equals 44.\newlineThis confirms the electrician needs to order 44 rolls of tape.
