The graph represents the function f(x) = x2 + 3x + 2.
If g(x) is the reflection of f(x) across the xaxis, g(x) = . (Write the function in standard form. Use ^ to indicate an exponent.)

Best ResponseYou've already chosen the best response.2hint: if you reflect f(x) over the x axis to get g(x), then g(x) = f(x)

Best ResponseYou've already chosen the best response.2let's say f(x) = x^2  6x + 10 multiply both sides by 1 to get 1*f(x) = 1*(x^2  6x + 10) 1*f(x) = 1*x^2 1*(6x)  1*10 ... distribute f(x) = x^2 + 6x  10  If you compare f(x) = x^2  6x + 10 to f(x) = x^2 + 6x  10, you'll find that all of the signs have been flipped. Eg: +x^2 goes to x^2 or 6x turns into +6x So if f(x) = x^2  6x + 10, and we flip it over the x axis to get g(x), then g(x) = f(x) g(x) = x^2 + 6x  10 this isn't the answer as it's just an example

Best ResponseYou've already chosen the best response.0so then would i do g(x)=x^2 + 3x + 2?

Best ResponseYou've already chosen the best response.2that's f(x) to find g(x), you simply swap all of the signs on f(x)

Best ResponseYou've already chosen the best response.0so then it would be g(x)=x^23x2? right? sorry im pretty bad at algebra

Best ResponseYou've already chosen the best response.2don't forget about the first term x^2

Best ResponseYou've already chosen the best response.0so that needs to have a negative sign in front of it also?

Best ResponseYou've already chosen the best response.2yes because in f(x), the x^2 is like +x^2

Best ResponseYou've already chosen the best response.2the +x^2 just turns into x^2

Best ResponseYou've already chosen the best response.2so what I'm saying is that f(x) = x^2 + 3x + 2 turns into g(x) = x^2  3x  2

Best ResponseYou've already chosen the best response.2all of the signs flip
