Step-by-step explanation:
13. The difference of two matrices is the term-by-term difference. For example, the bottom right term is the difference of the bottom right terms ...
(-6) -(5) = -11
__
14. The scalar multiple of a matrix is the scalar multiplied by each term of the matrix. For example, the upper right term is ...
3(1) = 3
__
15. The matrix product is the dot product of the rows of the left matrix with the columns of the right matrix. For example, the product term in row two, column one is the dot product of row 2 of C and column 1 of B:
[9, -2, 4]·[-2, -7, 10] = 9(-2) +(-2)(-7) +4(10) = -18 +14 +40 = 36

ANSWER
The exponential function is
EXPLANATION
Let the exponential function that is represented by the values in the table be of the form,
The points in the table must satisfy this exponential function.
We substitute the point,
to get,
This implies that,
Our function now becomes,
We gain, plug in another point yo find the value of b too.
Let us substitute
This implies that,
We divide through by 3 to obtain,
Therefore the function is,
The correct answer is A.
