If a function contains the origin, then its inverse contains the origin.

I believe that the statement is true. If a function contains the origin, then its inverse contains the origin. It is based on the definition of an inverse relation which states that "If the graph of a function contains a point (a, b), then the graph of the inverse relation of the function contains the point (b, a)." Hope this helps.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
