Is 1x^2-2x-15=0 a vertical stretch or compression HURRY PLEASE!!

NEITHER vertical stretching NOR vertical compression

Step-by-step explanation:

f(x) = 1x^2-2x-15  =  1x^2 - 2x - 15

Because the coefficient of the x^2 term is 1, there is NEITHER vertical stretching NOR vertical compression.

Here f(x) = 1x^2 - 2x - 15 = x^2 - 2x + 1 - 1 - 15  =  (x - 1)^2 - 16

represents a parabola whose vertex is at (1, -16), which opens up, and which has stretching in neither direction (horizontal or vertical).

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
