Answer:
First row. = -393 74 287
Second row = 471. 162 91
Third row =251 222 - 349
Step-by-step explanation:
For the first row
Cofactor of 12= (-8*15)-(21*13)
= -120-273
= -393
Cofactor of 23 = (11*15)-(7*13)
= 165-91
= 74
Cofactor of -6 = (11*21)-(-7*8)
= 231+56
= 287
For the second row
Cofactor of 11 = (23*15)-(21*-6)
= 345+126
= 471
Cofactor of -8 = (12*15)-(7*-6)
= 120 + 42
= 162
Cofactor of 13 (12*21)-(23*7)
= 252-161
= 91
For third row
Cofactor of 7= (23*13)-(-8*-6)
= 299-48
= 251
Cofactor of 21 = (12*13)-(11*-6)
= 156+66
=222
Cofactor of 15 = (12*-8)-(11*23)
= -96 - 253
=- 349
Answer:
the range of this function is [-7, 2) (Answer A)
Step-by-step explanation:
The "range" of this function is the list of all values that the function can take on according to the rule shown in the graph. The smallest such value (the smallest y-value) is -7, obtained when x = -2. The largest is just less than 2; we know this because there is an empty circle at (1, 2) instead of a shaded circle.
Thus, the range of this function is [-7, 2)
