find given the funcrion k described by k(x) =12x, find each of the following (a) k(-19),(b0 K (10)(c) k(21),k(-19)=

Answer 1

k ( x ) = 12 x

k ( - 19 )

x = - 19

k = 12 * ( - 19 ) = - 228

k ( - 19 ) = - 228

k ( 10 )

x = 10

k = 12 * 10 = 120

k ( 10 ) = 120

k ( 21 )

x = 21

k = 12 * 21 = 252

k ( 21 ) = 252
