The function f(x)equals2.8 startroot x endroot plus 19.9 models the median height, f(x), in inches, of boys who are x months of age. the graph of f is shown to the right. complete parts a through c below.
according to the model, what is the median height of boys who are 35 months old? use a calculator.
the median height of boys who are 35 months using the model is approximately

(type an integer or decimal rounded to the nearest tenth as needed.)

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
