  2. 1.5 Quadratic Functions and Geometric Transformations Let f be the function given by the graph to the left. Determine the graph of: y = f(x – 1) y = -f(x) y = f(x) + 2 y = -f(x + 1) y = f(x – 2) + 1

  3. 1.5 Quadratic Functions and Geometric Transformations If 200 ft. of fence is used to enclose a rectangular plot of land using an existing wall as one side of the plot, find the dimensions of the rectangle with maximum enclosed area.

  4. 1.5 Quadratic Functions and Geometric Transformations A rectangle is 3 ft longer than it is wide. If each side is increased by 1 ft, the area of the new rectangle is 208 sq ft. Find the dimensions of the original rectangle.

  5. 1.5 Quadratic Functions and Geometric Transformations Sally invests $20,000. She puts part of the money into an account that pays 4% annually, but she can withdraw from it without penalty, and she puts the rest into an account that pays 6% annually. • Write an equation that describes the total interest, I, Sally receives at the end of 1 year in terms of the amount A invested at 6%. • If Sally’s annual interest is $1086, how much of her original $20,000 did she invest at 6%?

  6. 1.5 Quadratic Functions and Geometric Transformations A rectangular pool with dimensions 25 by 40 ft is surrounded by a walk with a uniform width. If the area of the walk is 504 sq ft, find the width of the walk.
