The intercept (factored) form a parabola. y= a(x+r)(x+s)1. how does the value of 'a' affect the graph of a parabola2. how does the values of 'r' and 's' affect the graph of a parabola

The a value affects the graph by vertically stretching or compressing the graph.
The r and s values affect the zeros, or x intercepts of the parabola, and therefore the vertex.
Hope this helps!
