I REALLY NEED HELP FAST! Name the marked angle in 2 different ways.

What is the inverse of the function f(x) = 2x + 1?

In which direction does the left side of the graph of this function point? a(x) = 3x - x2 + 4x - 2

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.
