Represent the following system of linear equations as a single matrix equation of the form a = b,
where a is a 3 × 3 matrix, and x and b are 3 × 1 column matrices.
x+ 3y + 2z = 8
x− y + z = −2
2x+ 3y + 3z = 7

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
