y = a(x - h)2(sqaured) + k
Where would I put a number in order to stretch or compress the graph vertically in the equation above? And what does the a represent?
y = a(x-h)^2 + k
the value of "a" controls the vertical stretch or compression
if │a│ > 1 you have a stretch
if │a│ < 1 you have a compression
Thanks :D
To stretch or compress the graph vertically in the equation y = a(x - h)² + k, you would need to modify the value of "a".
The "a" in the equation represents the vertical stretch or compression factor. It determines how much the graph of the equation is stretched or compressed vertically.
If "a" is greater than 1, the graph will be vertically stretched. The larger the value of "a", the greater the stretching effect.
If "a" is between 0 and 1, the graph will be vertically compressed. The smaller the value of "a", the greater the compression.
If "a" is negative, it will also result in a vertical reflection of the graph.
