Given:

P = 2l + 2w;

P stands for perimeter; l stands for length; w stands for width

A) Write the function, using function notation, that Mr. Frame can use to find the perimeter of any window with a length of 5 ft, given the width.

f (w) = 2 (5) + 2w

f (w) = 10ft + 2w

B) Write the function, using function notation, that Mr. Frame can use to find the perimeter of any window with a width of 3 ft, given the length

f (l) = 2l + 2 (3)

f (l) = 2l + 6ft
