Best ResponseYou've already chosen the best response.1a is like a scale factor, it determines how skinny or wide the graph is kind of like the slope

Best ResponseYou've already chosen the best response.0so it should be x infrotn of (1) etc?

Best ResponseYou've already chosen the best response.1no i was replacing x with 1 because the function passes through the point (1,16) where the x_value is 1

Best ResponseYou've already chosen the best response.0then 1(1) etc, ? i got confused with ax , but i get it the you replace it.

Best ResponseYou've already chosen the best response.1ah ok lets say you have a parabola y = (x1)^2 it has one zero at x=1 right? but what about y = 5(x1)^2 it also has one zero at x=1, however its a different function, its a narrower parabola so given the zeroes we can put the function into factored form but we dont know how the graph looks thats where the a comes from. the point given allows us to solve for a thus giving us the entire function

Best ResponseYou've already chosen the best response.1oh ok same one so you substituted the x,y values in from the point they gave you then you solve for a, get it by itself

Best ResponseYou've already chosen the best response.0what i got right now 16=a(1)(1+3)(11)

dumbcow

Best ResponseYou've already chosen the best response.1ok use PEMDAS do the parenthesis first (11)^2 = (2)^2 = 4

anonymous

Best ResponseYou've already chosen the best response.0to what equipon. 16=2x(x+3)(x1)^2?

dumbcow

anonymous

Best ResponseYou've already chosen the best response.0you looking for the fourt root

dumbcow

Best ResponseYou've already chosen the best response.1no its a fourth degree polynomial it just means our function has a x^4 term

Best ResponseYou've already chosen the best response.1i dont know what you mean you just did it answer is f(x) = 2x(x+3)(x1)^2
