IF `A = {1, 2, 3, 5, 7)`, and `B = {x^2 : x in A}`

If A = 3x^(2) + 5x -3 and B = 5x^(2) -7 , then 2A -B is _____

If A = 4x ^(2) + 7x -1 and B =-x ^(2) -5x +3, then what is 3/2 A -2B ?

If A = 4x^(3) - 5x + 7, B = 2x^(3) -x^(2) + 3 and C = 5x^(3) - 8x^(2) + 10 , then A - 2B - C is

If g(x)=[(1,1),(2,3),(3,5),(4,7)] is a function from A={1,2,3,4} to B={1,3,5,7} and g(x)=ax+b, then find "a" and "b"?

Simplify: 5x - 2x ( x- 1) A. 3x - 2 B. 3x + 2 C. 7x + 2x^(2) D. 7x - 2x^(2)

If B={(1,1),(2,3),(3,5),(4,7)}" is a function from ,A={1,2,3,4}" to "B={1,3,5,7} ,g(x)=ax+b " find "a" and "b?
