can you solve this equation please?

Question

y = |x|

what are the x and y intercept(s)?
i know it's the basics but i've totally forgotten how to deal with determinants. please help.

Answer 1

I asked a similar question earlier. The intercepts both are the origin (0, 0). The graph is a 'V' shape where the lines are in the first and second quadrants, meeting at origin which is the vertex of the 'V'. The lines are mirror images of each other. One line represents y = -x and the other represents y = x

Answer 2

That's not a determinant symbol. That's absolute value, where for any value of x, y is the positive form of x. To determine the x and y intercepts, just substitute 0 in for one, which will give you 0 for the other. So the x and y intercepts are both 0 b/c the point where this graph crosses either axis is at the origin (0,0).

Answer 3

determinatns? I assume | | is the absolute value operator, so that |x| = x if x >= 0, = -x if x<0.
so the x-intercept and the y-intercept are both 0.

Answer 4

The origin, (0, 0), is the intercept, for both axes.

For positive x --> y = x, a ray from the origin with slope 1

For negative x -- > y = -x, a ray to the origin with slope -1.

Answer 5

We've y = |x|:

== For x intercept(s) put y = 0 above ==> |x| = 0 ==> the only x-intercept is (0,0)

== For y-intercept put x = 0 above ==> y = 0 ==> we get the same point as above (0,0).

Answer 6

???
'Determinants'?? That looks like y equals absolute value of x to me ☺ And the x and y intercepts are both at the origin.

Answer 7

x ...-2 -1 0 1 2...
y ...2 1 0 1 2...

the graph is a symmetrical V-shape, found in the positive y axis whose vertex is at the origin

Answer 8

y=x or y=-x
