Answer:
5
Step-by-step explanation:
evaluate f(4) by substituting x = 4 into f(x) and g(2) by substituting x = 2 into g(x)
f(4) = (3 × 4) - 3 = 12 - 3 = 9
g(2) = (2 × 2 ) = 4
f(4) - g(2) = 9 - 4 = 5
Answer:
2x^2+7
Step-by-step explanation:
Cause it has only two monomials
Answer:
Option C
Step-by-step explanation:
- For the matrix A of order
to be invertible, its determinant must not be equal to zero, |A|
0,
exists if- AC = CA = I, where I is identity matrix.
- The homogeneous equation with coefficient matrix A has a unique solution:
AB = 0, B = 
Thus, B = (0, 0, 0......., 0) is a unique solution
2. The non - homogeneous equation system with coefficient matrix A has a unique solution:
For an equation- AY = D
Y =
is a unique solution
3. Every non homogeneous equation with coefficient matrix A is not consistent as:
For an equation- AY = D, has a solution.l Thus coefficient matrix is inconsistent whereas augmented matrix is.
4. Rank of matrix A = n, Thus the column space of A is 
5. Since, column space of A =
, thus x→xA is one-to-one
