Answer:
x = 0.5
Step-by-step explanation:
2x - 3 = - 2 ( add 3 to both sides )
2x = 1 ( divide both sides by 2 )
x = = 0.5

Choices A and B have typos in them, so its not clear what you're trying to say for those parts. However, the domain of is
meaning that x can be 0 or larger. In other words, we can't have x be negative. Similarly, y is the same story because
has the inverse
, but only when
, so therefore
as well. In short you can say both x and y are nonnegative.
To summarize so far, the domain is and the range is
Since x = 0 and y = 0 are the smallest x and y values possible, this means (x,y) = (0,0) is the left-most point or where the graph starts. This is the origin. Choice C is a true statement.
Choice D on the other hand is <u>not</u> a true statement. Graph out and you'll see that a straight line does not form, but instead a nonlinear curve that grows forever. That growth gradually diminishes as x gets larger. Algebraically you can pick three points from the function and show that the slopes are different. Say the three points are P, Q and R. If you can show that slope of PQ does not equal slope of QR, then the function is not linear.
