WebQuadratic forms a function f : Rn → R of the form f(x) = xTAx = Xn i,j=1 Aijxixj is called a quadratic form in a quadratic form we may as well assume A = AT since xTAx = xT((A+AT)/2)x ((A+AT)/2 is called the symmetric part of A) uniqueness: if xTAx = xTBx for all x ∈ Rn and A = AT, B = BT, then A = B When using substitution, allinstances of the variable being substituted for must be replaced. The same applies when dilating a function. For example, if are working with a function that has multiple x terms, such as and dilating it horizontally by a factor of 4 then every instance of must have the dilation equation … See more In looking at the coordinates of the two corresponding points identified in the graph above, you can see that the y-coordinate has not … See more Look at the coordinates of the corresponding A points on the green and red graphs above. The x-coordinate has not changed, but the y-coordinate has been stretched to be three times further away from the x-axis. … See more The image above shows the result of two dilations. The green curve has been dilated bothhorizontally and vertically to produce the red … See more A negative dilation factor will cause the graph to be reflected about an axis, as well as stretched or compressed. For the vertical dilation example above, if the dilation factor had … See more
