Do you know how to graph f(x)=x^2?
OpenStudy (freckles):
for range think y values
OpenStudy (thedj4jc):
No and it's not x to the second power, it's x times 2.
OpenStudy (freckles):
so its f(x)=2x?
OpenStudy (freckles):
ok well do you know how to graph f(x)=2x?

No

Do you know that f(x)=mx+b is a linear function?
OpenStudy (freckles):
f(x)=mx+b where m is the slope and b is the y-intercept
OpenStudy (freckles):
you have f(x)=2x+0
so your y-intercept is?
and your slope if ?
OpenStudy (freckles):
is*

OpenStudy (thedj4jc):
y is 0 and 2 is m???
OpenStudy (freckles):
yes
OpenStudy (freckles):
so use that info to graph your line
OpenStudy (freckles):
but you know your lines goes on forever and ever in either direction
OpenStudy (freckles):
So you actually already know the range
but if you aren't convinced then I say still graph it

Is it C, y >= 0?
OpenStudy (freckles):
Well it goes on in either direction forever and ever
that just says the line starts above the x-axis and goes in the positive direction forever and ever
OpenStudy (freckles):
|dw:1427392093666:dw|
this line goes on in either direction forever and ever
