Question

g(x) = lxl
please help!

Answer 1

to do what?

Answer 2

i have to make a graph but dont know how to get the values...

Answer 3

One simple way is to make a table of x and g(x) values; try x values from -10 to 10, to start

Answer 4

So, for example, we can find the g(x) values for x=-10, x=-5, x=0, x=5, x=10

x=-10, g(x)=10
x=-5, g(x)=5
x=0, g(x)=0
x=5, g(x)=5
x=10, g(x)=10

So, with absolute value, we find that for x=0, g(x)=0; for positive values of x [x>0], we find that g(x)=x, but for negative values of x [x<0] we find that g(x) = -x

If you graph those values, it should look like a V, with the crux of the v at point x=0, g(x) = 0, and the V should be symmetric, since a number c and a number -c will have the same g(c) value

thank you so much this was really helpful!
