Answer:
I believe it's C I had this on my test and I got it right
I think it's because if you can't caculate it or you want a rough answer you can estimate. For example you are estimating the height of a tall building. You would just want to estimate it first.
Answer:
A. 1
Step-by-step explanation:
I see only one red function line in the graph. this line represents the simple function y = 1, for x in the interval [-2,1].
the domain of a function defines the possible values for x, and the range of a function defined the possible values for y.
this function has only one possible value for y : 1
so, only A applies.
The parent function has a slope of 1 or -1 from any point to the vertex. In the problem, we are given the points
(–2, 3) and (–1, 0)
The slope between the two points is
m = 0 - 3 / (-1 - (-2))
m = 3
The slope is greater than 1. Therefore, the graph has been dilated by a scale factor other than 1.
