(1 point) a is an n×n matrix. check the true statements below: a. a number c is an eigenvalue of a if and only if the equation (a−ci)x=0 has a nontrivial solution x. b. finding an eigenvector of a might be difficult, but checking whether a given vector is in fact an eigenvector is easy. c. a matrix a is not invertible if and only if 0 is an eigenvalue of a. d. to find the eigenvalues of a, reduce a to echelon form. e. if ax=λx for some vector x, then λ is an eigenvalue of a.

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
