Whats the domain for this equation?

Strictly speaking an equation does not have a domain. A function does. Though it may make sense to speak about a solution set to this equation over a domain.

The following could be helpful towards an The equation has two sides. The left hand side is a non-linear function and the right hand side is a line with slope -1 and y-intercept of 1.

The function has a domain over all Reals x for which it holds so the domain of the nonlinear function is .

The domain of the linear function 1-x is all Reals:

So, together you could say the equation's solutions are defined over the domain .

Lmk if you have questions.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

-2 is the right
