The answer is A) -23
A is a 1x3 Matrix while B is 3x1 Matrix. Since A has the same number of rows as that of the number of columns of B, they can be multiplied. A has 1 row and B has 1 column. So, their products is a 1x1 Matrix.
Simply, the operation is:
(3)(-1) + (-2)(4) +(6)(-2) = -23
The domain of a function is the set of input values the function can take
The domain is all set of real numbers
<h3>How to determine the domain</h3>
The expression is given as:
Factorize the numerator of the expression
Simplify: Cancel out the common terms
The above expression can take any value of x.
Hence, the domain is all set of real numbers

Answer-
B the relation is not a function
Answer:
For vectors given by their components: A = (Ax, Ay, Az) and B = (Bx, By, Bz), the scalar product is given by A · B = AxBx + AyBy + AzBz Note that if θ = 90°, then cos (θ) = 0 and therefore we can state that: Two vectors, with magnitudes not equal to zero, are perpendicular if and only if their scalar product is equal to zero.
