f x = 8 x + 4 The function f gives the estimated height, in feet, of a willow tree

Question

f x = 8 x + 4 The function f gives the estimated height, in feet, of a willow tree x years after its height was first measured. Which statement is the best interpretation of 4 in this context?

Accepted Answer

Choice D is correct. It's given that the function f x = 8 x + 4 gives the estimated height, in feet, of a willow tree x years after its height was first measured. For a function defined by an equation of the form f x = m x + b , where m and b are constants, b represents the value of f x when x = 0 . It follows that in the given function, 4 represents the value of f x when x = 0 . Therefore, the best interpretation of 4 in this context is that the estimated height of the tree was 4 feet when it was first measured. Choice A is incorrect and may result from conceptual errors. Choice B is incorrect and may result from conceptual errors. Choice C is incorrect and may result from conceptual errors.
