If f(x) is the height, in cm, of a sunflower plant which is x days old, which of the following statements best describes the meaning of f(60) = 210? The height of the sunflower plant is 60 cm when it is 210 days old. The height of the sunflower plant is 210 cm when it is 60 days old. The height of the sunflower plant is 210 cm when it is 3.5 days old. The height of the sunflower plant is 60 cm when it is 3.5 days old. @whatdoesthismean

    okay since f(x) is the hieght, and it equals 210, 210 is the number of cm

    The first five terms of a sequence are shown below. 4, 7, 10, 13, 16 If the nth term of this sequence is represented by f(n), which of the following functions best represents this sequence? f(n) = 3n - 1; n ≥ 1 f(n) = 3n + 1; n ≥ 1 f(n) = 4n - 1; n ≥ 1 f(n) = 4n + 1; n ≥ 1

    This is more of trial and error.

    SO basically you take the nth term (for example 4 is the first term, and etc.) and put it in for x. so ill do it for B. f(1). it results in 4. This works so you try it for the next nth term, which is 2.

    and since when you plug in 1 for n, C and D also do not work, those are ruled out, and you have B for your answer :)
