(1 point) By completing the square, put the equation x2 - 9y- + 2 + 14x - 6z =-58 into the standard form a(x - Xo)' + b(y - yo)' + c(z - zo) +1 2. f (x, y ) = 1+y 3. f(x, y) = 1+ 2x2 + 2yz 4. f ( x, y) = V4x2 + 1(1 point) Without a calculator or computer, match the functions with their graphs in the figures below. Note that two of the functions do not have a matching graph. (a) z = 2+ x+, ? (b) z = 2(x2 + 1) ? (c) z = 2 ? v (d) z = -2(x- + yz) ? (e) z = -2 ? v (f) z = 2 - x ? X 2. X
