Answer:
x ≥ 1
Step-by-step explanation:
There are no domain restrictions on a(x), so we can find the domain of the composite function by looking at that composition:
The argument of the square root function must be non-negative, so we must have ...
3(x -1) ≥ 0
x -1 ≥ 0 . . . . . divide by 3
x ≥ 1 . . . . . . . add 1
The domain of b(a(x)) is x ≥ 1.
Answer:
a) enlargement
b) scale factor is 2
Step-by-step explanation:
As we can see, we went from the block to the red figure
a) Since the red figure is bigger, then what we have is an enlargement of the original figure
b) As we can see, the coordinates of the red is two times the value of the coordinates of the black
So, we can conclude that what we have as a scale factor is 2
1/2, 4/8. If in decimal form, you can also do 0.5 or 0.500
