Best ResponseYou've already chosen the best response.0f(x) = 3 x^2 when x = 0 f(x) = 0 so what is the axis of symmetry of this function?

Best ResponseYou've already chosen the best response.0no its x = 0  in other words its the f(x) ( or y axis) dw:1434834269396:dw

Best ResponseYou've already chosen the best response.0the axis of symmetry is a vertical line for these functions and is x = something

Best ResponseYou've already chosen the best response.0ok shouldn't I use b/2a to find it??

Best ResponseYou've already chosen the best response.0yes  but in the case of 3x^2 you needn't use it but you can  note that b = 0 in this case so b/2a = 0/6 = 0

Best ResponseYou've already chosen the best response.0b / 2a = (4) / 2 = 4/2 = 2 yes

Best ResponseYou've already chosen the best response.0for h(x) its 4 / 2* 2 = 4 / 4 = 1

Best ResponseYou've already chosen the best response.0Given the function f(x) = x2 and k = 2, which of the following represents a horizontal shift? f(x) + k kf(x) f(x + k) f(kx)

Best ResponseYou've already chosen the best response.0without giving you a direct answer here is an example if we have f(x) = x^2, f(x+1)^2 will shift the graph horizontally 1 unit to the left

Best ResponseYou've already chosen the best response.0* that is f(x + 1) = (x + 1)^2
