This equation models exponential decay.
We know this because the exponent in the equation is negative, showing us that the growth is “negative”, meaning it represents decay.
Hope this helps!
I have no idea ☠️ i just need to answer questions to be able to ask questions
It represents the absolute value of negative 5 which is positive 5
Basing on the description, a parabola opening up with vertex at origin, the formula with vertex at origin is used, x^2 = 4py. p is the focus and so with the dimensions given, we obtain a 0.25 and that is the distance of the focus to the vertex.
