If gx 2x2 x 4 find g 2 A 12 B 16 C 20 D 10 Simplify 2xy3x

If g(x) = 2x^2 - x + 4 find: g (2) (A) 12 (B) -16 (C) -20 (D) 10 Simplify: 2xy(3xy + 5x) - 4x^2y^2 (A) 12x^6y^5 (B) 6xy + 10x^2y - 4x^2y^2 (C) 2x^4y^2 + 10x^2y (D) 2x^2y^2 + 10x^2y

Solution

g(x) = 2x^2 - x + 4

g(2)

plug x = 2 in the function

g(2) =2(2)^2 - 2 + 4

= 8 - 2 + 4

= 10

option D is correct
