What is the range of the function y = x2? all real numbers x ≥ 0 y ≥ 0
Do you know how to graph f(x)=x^2?
for range think y values
No and it's not x to the second power, it's x times 2.
so its f(x)=2x?
ok well do you know how to graph f(x)=2x?
No
Do you know that f(x)=mx+b is a linear function?
f(x)=mx+b where m is the slope and b is the y-intercept
you have f(x)=2x+0 so your y-intercept is? and your slope if ?
is*
y is 0 and 2 is m???
yes
so use that info to graph your line
but you know your lines goes on forever and ever in either direction
So you actually already know the range but if you aren't convinced then I say still graph it
Is it C, y >= 0?
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
