Some people believe that biorhythms can help explain one's emotional, intellectual, and physical aptitude on any given day. For example, the curve below models the physical biorhythm, P, for a person born on day t = 0 . Approximately how long is one cycle of the physical biorhythm?

do i do it on a graph?

step-by-step explanation:

da freeck kinda math is this just drop out

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
