A hyperbola with the right hand side equal to zero. One variable is squared and the other variable is missing. The right hand side must be positive. If the right hand side is zero, then it is a line (x2 = 0 so x = 0) and if the right hand side is negative (x2 = -1), then there is no graph.
Does a hyperbola have to equal 1?
When the transverse axis is horizontal (in other words, when the center, foci, and vertices line up side by side, parallel to the x-axis), then the a2 goes with the x part of the hyperbola's equation, and the y part is subtracted. ... In "conics" form, an hyperbola's equation is always "=1".
Can a be negative in hyperbola?
This is the equation we use for horizontal hyperbolas—x is the positive term, and so the graph opens to the left and right. The only difference for an up-and-down hyperbola is that now y is positive and x is negative. ... Hyperbolas have a center at (h, k), which will be right in the middle of the two curves.
