Question 523528
It appears your equation is:
{{{ y = (4/3)*x + 7 }}}
so
x can range from -infinity to +infinity
.
However, if your equation in fact is:
{{{ y = 4/(3*x) + 7 }}}
If so, x cannot = 0 cannot because that would be dividing by 0.
So the domain is -infinity to 0, and 0 to +infinity.
.
In the following graph;
the red line is y = (4/3)x+7
the green line is y=4/(3x)+7
.
{{{ graph(500,500,-10,10,-10,10,4/3*x+7,4/(3*x)+7) }}}
