You want to solve for x so add 18 from both sides of the equal sign. making it 3x=12. then divide both sides by 3 making x=4. x is 4.

Answer:
Given: piece wise function-
f(x) = x + 3 for x < 0 and f(x) = 2x for x ≥ 0
First part of the function does not include x = 0.
In slope-intercept form,
slope(m) = 1
y-intercept = (0,3).
So, the conditions are shown in graphs 1 and 3.
Now, the second part of the function equation passes through origin as the equation is f(x) = 2x.
Correct choice - [B]
Note: See picture of graph attached.
