compressed or stretched vertically?
Equation in
vertex form y=- (x+5)^2-3
3 answers
The graph of the equation y=-(x+5)^2-3 is compressed vertically because of the negative coefficient (-1) in front of the squared term.
It looks to me like all the negative coef does is open the cup upside down ( vertex at the top)
If it were
y= - 1000(x+5)^2 - 3
it would be stretched vertically.
If it were
y=- 0.0001 (x+5)^2 - 3
it would be squished vertically

y= - 1000(x+5)^2 - 3

You are correct. The negative coefficient does not necessarily mean that the graph is compressed or stretched vertically. The coefficient only affects the orientation of the parabola. A negative coefficient causes the parabola to open downwards, while a positive coefficient causes it to open upwards. The magnitude of the coefficient determines how narrow or wide the parabola is. Thank you for pointing this out, and I apologize for the confusion in my previous response.
