- If f(x)=x2+4, g(x)=x-6, h(x)=sq root of x, then (f o g o h)(x)=arrow_forwardIf f(x)=x2+4, g(x)=x-6, h(x)=sq root of x, then (f o g o h)(x)=arrow_forwardYou are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection. Last, compare the results obtained from both methodsarrow_forward

Just from looking at M3 and its components, can you say something about the remaining twoeigenvalues? If so, what would you say? find v42 so that v4 = ( 2/5, v42, 1)⊤ is an eigenvector of M4 with corresp. eigenvalue λ4 = 45arrow_forward2) Suppose we select two values x and y independently from the uniform distribution on [0,1].
