Answer:
B.
Step-by-step explanation:
the visible line is the defined function.
this line goes from x=1 to x=4, and has the functional results from y=1 to y=7.
the domain is the valid interval of the input variable (typically x), while the range is the valid inescapable of the result variable (typically y).
so, B is the right answer.
Answer:
the answer is d. fjdkdkddkdkdkd
If both (1,2) and (-3,-3) were reflected across the y-axis, the x coordinate would reverse. (1,2) would become (-1,2), and (-3,-3) would become (3,-3). In this case, the answer would be A.
Answer:
Hi
f(x)= x^2-2x+4
f(2a)= (2a)^2-2(2a)+4 = 4a^2-4a + 4 = 4(a^2-a+1)
