147 let us let u = [ 47 21 -3 and a= 0 1 -2 . is u in the subset of r | 1 3 - 2 spanned by the columns of a? why or why not? select the correct choice below and fill in the answer box to complete your choice. (type an integer or decimal for each matrix element.) o a. no, the reduced row echelon form of the augmented matrix is , which is an inconsistent system. ob. yes, multiplying a by the vector writes u as a linear combination of the columns of a.

i think it is c, not positive though

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
