Need ! question 1. what are the dimensions of the matrix? {6,2,8,3} a: 1x4 b: 1x1 c: 4x4 d: 4x1,

As written, most likely 1 row and 4 columns: 1x4, selection A.


My calculator might recognize this as a vector (or a list of 4 elements). It would like double brackets to make it a matrix: [[6,2,8,3]] with 1 row. My math program would treat it as either a 1x4 vector or a 4x1 vector depending on the expression it might get used in.

You need to consult your text or other curriculum material to determine the intended meaning of this expression.

Point is the only one not undefined
