Let T be a linear transformation from R³ into R³. Find T-1
T(x1x₂x3) = (2x1-X3, X₁ + X₂ X3, X2-3X3)
T(X₁₁X₁₁X3) = (2x₁+x₂ −X3, −3x₁+6x₂−x3, −X₁+2×₂-2x3)
b. T(x1x2x3) = (2x₁ + x₂ -2X3, X₂-X3, X1 + X3)
c. T(x₁,x₂₁x3) = (2x₁ + x₂ -2X3, X₂-X3, -X₁ + X3)
d. T(x1,x2x3) = (4x₁-2×₂-X3, X₁-X₂, −3x₁+2x₂ + x3)
T(X₁, X₂2₁×3) = (-x₁ + 3x₂ + 3x3, −3x₁-x₂ + 4x3,2x₁ − ×2 −X3)

Show two examples for the polynomials
Suppose T: P3→R³ is a linear transformation whose action is defined by
a-2b+5c-4d
T(ax³ + bx²+cx+d) = 3a-b+5c-2d
a-b+3c-2d
Determine whether T is one-to-one and/or onto. If it is not one-to-one, show this by providing two polynomials that have the sam
the image of T. Use the '^' character to indicate an exponent and x as the variable for polynomials, e.g. 5x^2-2x+1
T is one-to-one
T is onto
