Use a Riemann Sum with five subintervals of equal length (n = 5) to approximate the area between the graph of f(x) = 9 – 2x and the x-axis on the interval [0, 4]. Choose the representative points to be left endpoints.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

Which is an x-intercept of the graphed function? (0, 4) (–1, 0) (4, 0) (0, –1)

To diagonalize an nxn matrix a means to find an invertible matrix p and a diagonal matrix d such that a pdp d p ap or [1 3 dh epap 3 let a=-3 -5 -3 3 3 1 step 1: find the eigenvalues of matrix a "2's" step 2: find the corresponding eigenvectors of a step 3: createp from eigenvectors in step 2 step 4 create d with matching eigenvalues.
