Question

On the coordinate grid, the graph of y = 3x - 1 + 3 is

Answer 1

Step-by-step explanation:

the domain is the interval or set of all valid input values (values of x).

while the range is the interval or set of all valid result values (y values).

so, we don't need to look at the answer options dealing with y. the domain only concerns x.

and when you look at the graph it shows you that every number on the x-axis from all the way to the left to all the way to the right is valid (from -infinity to +infinity).

and the function itself (the cubic root of x) did not provide any theoretical limits. you can take the cubic root from any number, positive or negative.

therefore, the third answer option is correct (all x, where x is a real number).
