If a is a 6 × 6 matrix with dim(nulla) = s and dim(ima) = t, which of the following are possible values for s and t?
a) s = 0, t = 5
b) s = –3, t = 9
c) s = 2, t = 3
d) s = 6, t = 0

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
