Best ResponseYou've already chosen the best response.0We can let \(y = 0\) and then solve \(2x^2 + 4x + 2 = 0\).

Best ResponseYou've already chosen the best response.0if you solve the equation, u end up with (x+1)^2, so, the the function will be satisfied by 1, but twice....so it has one x intercept

Best ResponseYou've already chosen the best response.0Two intercepts. 2x^2 + 4 x + 2. The leading exponential power tells you how many intercepts will be present (in this case, it is 2) For example, if it were 3x^3 it would have 3 x intercepts

Best ResponseYou've already chosen the best response.02x^2+2x+1+0 or, x^2_2x+1=0 or, (x+1)^2=0 or, X+1=0 or, x= 1
