@angle if you could double check me on this one that would be appreciated ;; non-rigid implies that the graph is being stretched or shrunk, which eliminates c/d and there's no vertical transformation so...a? the answer a doesn't seem exactly right either
The terminology for what it means to be "stretched horizontally" versus "stretched vertically" is vague. Because technically the graph is doing both. Therefore, in order to pick between A and B you need to understand the difference between "stretched horizontally" and "stretched vertically". Here is a picture I found that describes this: |dw:1512439717619:dw|
From the picture we can see that: - Stretching horizontally Does Not change the y-intercepts, but Does change the x intercepts - Stretching vertically Does change the y-intercepts, but Does Not change the x intercepts Now let's see how the given equation changes when we fiddle with the number where the (3) is... y-1 = -(x+1)^2 has y-intercept at y = 0 and x intercepts at x = -2, 0 y-1 = -(2x+1)^2 has y-intercept at y = 0 and x intercepts at x = -1, 0 y-1 = -(3x+1)^2 has y-intercept at y = 0 and x intercepts at x = -2/3, 0 So with this, we can see that the y-intercept is Not changing, but the x-intercepts Are So this graph is being Horizontally stretched
@Vocaloid is correct
I'm sorry had to go for a little bit is it a?
yup :D
