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

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.

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.

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%?

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.
