Best ResponseYou've already chosen the best response.02. Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to Heinz the other key features of g(x). • g(x) = x3 – x2 – 4x + 4 • g(x) = x3 + 2x2 – 9x – 18 • g(x) = x3 – 3x2 – 4x + 12 • g(x) = x3 + 2x2 – 25x – 50 • g(x) = 2x3 + 14x2 – 2x – 14

Best ResponseYou've already chosen the best response.1sorrry xD I'm pretty sure the qualified helpers can help :) Firstly you should choose one of the g(x) functions to use

Best ResponseYou've already chosen the best response.1for the first part, when you want to find the 0's, you set g(x) = 0... then factorise and solve for x. So e.g. if you use the first one: g(x) = x^3  x^2  4x + 4 \[g(x) = x^3  x^2 4x + 4 \rightarrow x^3  x^2  4x + 4 = 0 \]

Best ResponseYou've already chosen the best response.1you can factorise that to get: dw:1436366996300:dw

Best ResponseYou've already chosen the best response.0@butterflydreamer so the answer is x= +2,1

Best ResponseYou've already chosen the best response.1hmm yeah, but only if YOU choose to use the first equation. I'd suggest you pick a different one on your own though :)

Best ResponseYou've already chosen the best response.0@butterflydreamer here is the other question. 3. Provide a rough sketch of g(x). Label or identify the key features on the graph.

Best ResponseYou've already chosen the best response.1when you identify the zeros of a function, the values of x will be your xvalues when y = 0. So basically, when g (x) = 0 , x = 2 , + 2 , 1 Note: (2, 0) , (2, 0), (1,0) are your xintercepts basically. looking at your relation: \[g(x) = x^3  x^2  4x+ x \] Can you see that your relation is a cubic? Since the highest degree is 3. Also note how x^3 is POSITIVE and not x^3. So it's positive curve.

Best ResponseYou've already chosen the best response.0Ok. So I how would I do the graph though? I will have to use a curved line correct?

Best ResponseYou've already chosen the best response.1so try to graph it.. knowing that it is:  a positive cubic curve  has 3 xintercepts at ( 2, 0) , (2, 0), (1, 0) OH i forgot, also work out your yintercept :) so when x = 0 , y= ? to do this we have : y = x^3  x^2  4x + 4 so set x = 0 and we get \[y = (0)^3  (0)^2  4(0) + 4 = ? \] TO SUMMARISE. To sketch a cubic: 1. identify if it is a positive/negative cubic curve (ask yourself if x^3 is + / ) 2. find xintercepts (set y = 0) 3. find yintercept (set x = 0) dw:1436369493931:dw

Best ResponseYou've already chosen the best response.04. Esmeralda is graphing a polynomial function as a parabola. Before she begins graphing it, explain how to find the vertex. Make sure you include how to determine if it will be a maximum or minimum point. Use an example quadratic function to help you explain and provide its graph.
