If `f(x)=x^2+4x-5 and A=[(1,2),(4,-3)] then f(A)=` (A) `[(0,-4),(8,8)]` (B) `[(0,-4),(8,8)]` (C) `[(1,1),(1,0)]` (D) `[(8,4),(8,0)]`

If, A=[(1,1,2),(0,-3,5),(-2,3,4)] ,then is 4A=[(4,4,8),(0,-12,20),(-8,12,16)] ?

Given the matrix A=[(x,3,2),(1,y,4),(2,2z)]. If xyz=60 and 8x+4y+3z=20, then A(adjA) is equal to (a) [(6,4,0,0),(0,6,4,0),(0,0,6,4)] (b) [(8,8,0,0),(0,8,8,0),(0,0,8,8)] (c) [(6,8,0,0),(0,6,8,0),(0,0,6,8)] (d) [(3,4,0,0),(0,3,4,0),(0,0,3,4)]

If A=[(2, 0,-3),( 4, 3, 1),(-5, 7, 2)] is expressed as the sum of a symmetric and skew-symmetric matrix, then the symmetric matrix is (a) [(2, 2,-4 ),(2, 3, 4),(-4, 4, 2)] (b) [(2, 4,-5),( 0, 3, 7),(-3, 1, 2)] (c) [(4, 4,-8),( 4, 6, 8),(-8, 8, 4)] (d) [(1, 0 ,0 ),(0 ,1 ,0),( 0, 0, 1)]

If f(x)=2x^(2)," find "(f(3*8)-f(4))/(3*8-4):

If f(x^(2) - 4x + 4) = x^(2) + 1 . Find f(1) if f(1) lt 8 .

If d/(dx)f(x)=4x^3-3/(x^4) such that f(2)=0. Then f(x) is (A) x^4+1/(x^3)-(129)/8 (B) x^3+1/(x^4)+(129)/8 (C) x^4+1/(x^3)+(129)/8 (D) x^3+1/(x^4)-(129)/8

If int_(0)^(a) (1)/(1+4x^(2)) dx = pi/8 , then a=

The range of f(x)=(x^(4))/(1+x^(8)) is (1)[0,oo)(2)[0,(1)/(2)](3)[0,1](4)(-oo,oo)

If A={:[(1,2),(-1,8),(4,9)]:}andX+A=0 , then X is equal to
