Suppose you want to crop (remove) 3 inches from the width of a photo. After you have cropped (reduced) the width of the photo by 3 inches, you resize the photo by making it 60% of its cropped size. a. If x is the original width of the photo and the function f determines cropped width of the photo (in inches) in terms of x, write a formula to define f. Preview b. If n represents the width (in inches) of the cropped photo, define a function g to determine the width (in inches) of the resized photo in terms of n.

Question
Transcribed Image Text:Suppose you want to crop (remove) 3 inches from the
width of a photo. After you have cropped (reduced) the
width of the photo by 3 inches, you resize the photo by
making it 60% of its cropped size.
a. If x is the original width of the photo and the
function f determines cropped width of the
photo (in inches) in terms of x, write a formula
to define f.
Preview
b. If n represents the width (in inches) of the
cropped photo, define a function g to determine
the width (in inches) of the resized photo in
terms of n.
Preview
c. What is the final cropped and resized photo
width if the original photo was 14 inches wide?
inches
Preview
d. Represent the value in (c), that is, the final
cropped and resized photo width for a photo that
was originally 14 inches wide, using function
notation? (Your answer will look something like
g(f(32)) or (f(g(19)).)
Preview
e. Complete the function definition for g o f that
combines the two processes (cropping followed
by resizing) into a composite function.
g(f(x)) =
