Question

Which is the graph of f(x) = StartRoot x EndRoot?

On a coordinate plane, a parabola opens up with a vertex at (0, 0).
On a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (2, 4).
On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).
On a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (4, 2).

Your answer is the third statement A coordinate plane with a line passing through (0,-1) and (1,0).

This is because we can rearrange The equation:-

x - y = 1:

x - y = 1:

X - y = 1

+ y

x = y + 1

- 1

y = x - 1

Now the equation is in the form Y= Mx+b, we can see that it would represent a line with a slope of 1 that has a y- intercept of -1

therefore we know it must go through (0,-1) because that is the point that represent the y- intercept being -1 but it is must be the third statement and not

y = X -1

Now the equation is in the form y = mx + b, we can see that it would represent a line with a slope of 1, that has a y intercept of -1.

Therefore we know it must go through

0, -1), because that is the point that represents the y-intercept being -1, but it must be the third statement and not the last statement because if we substitute (-1, 0) from the last statement into y = x - 1, we get 0 = 0 = -1 - 1, which is false.

I hope this helps! Let me know if you have any questions :)
