Best ResponseYou've already chosen the best response.0oh this is easy: set y = o and solve for x, you will get two solutions for x then substitute one solution to the original equation and solve for y do that again with the other x value and you have two coordinates

Best ResponseYou've already chosen the best response.0f(x) = 2x^2 4x set f(x) = 0 0 = 2x^2  4x 0 = 2x( x + 2) 2x = 0 or x + 2 = 0 x = 0 or x = 2 Substitute the first solution into the original equation f(x) = 2x^2  4x f(0) = 2(0)^2 4(0) f(0) = 0 * you got a y value for your first coordinate Substitute the second solution into the original equation f(x) = 2x^2  4x f(2) = 2(2)^2  4(2) f(2) = 2(4) + 8 f(2) = 8 + 8 f(2) = 0
