Ireally need ! 40 points plus ! !
graph the following piecewise function:
re-load page!
you actually neded to make a graph or tell me how to make it like where the lines go.

Basically, the equation if f(x)=x+4 for all values of x where -4≤x<3
but it is f(x)=2x-1 for all values of x where 3≤x<6

≤ means less than or eqal to
so just graph the line y=x+4 from x=-4 to x=3, but put an open circle at x=3
wait, since it's a line, graph the endpoints
f(-4)=0
f(3)=7
graph the points (-4,0) and (3,7)
connect them
put an empty circle around the point (3,7)

now the other function
y=2x-1
from 3 to 6
f(3)=5
f(6)=11
graph the points (3,5) and (6,11)
connect them with a line
since we have the < sign with the 6, put an empty circle around the point (6,11)
see graph below
black line is first function (x+4)
red line is 2nd function (2x-1)

Well in order to lose a pound you would have to burn 1,500 calories. the more calories you burn the more weight you lose. in order to lose 2 pounds you would have to run 4 hours and 28 minutes.
