Best ResponseYou've already chosen the best response.1yes... but you need to calculate the derivative of f to find the relative max/min of the function.

Best ResponseYou've already chosen the best response.0its okay :) so you don't know how to do it? :(

Best ResponseYou've already chosen the best response.0i know how to do it on a calculater ..but i left it at a friends house ://

Best ResponseYou've already chosen the best response.1oh... so you're allowed to use the max/min functions of a graphing calculator?

Best ResponseYou've already chosen the best response.1since you don't have your graphing calculator with you, use this online one.... https://www.desmos.com/calculator i've also included the graph of your function here:

Best ResponseYou've already chosen the best response.1it looks like you have a relative max at x=4 and a relative min at x=0

Best ResponseYou've already chosen the best response.0yeah, but that's not one of my options :(

Best ResponseYou've already chosen the best response.1the function you gave at the start does not coincide with those choices...

Best ResponseYou've already chosen the best response.1i double checked with this function you gave at the start: \(\large f(x)=x^3+6x^236 \) f has a relative max at x=4 and a relative min at x=0.

Best ResponseYou've already chosen the best response.1f(4) = 4 so (4, 4) is a relmax f(0) = 36 so (0, 36) is a relmin

Best ResponseYou've already chosen the best response.1i'm sorry.... i'm absolutely sure of my answer here.. even the calculator verifies my answer.... is this the function we started with correct?

Best ResponseYou've already chosen the best response.0What is a cubic polynomial function in standard form with zeros 1, –2, and 2?

Best ResponseYou've already chosen the best response.1do you know how to multiply out binomials?

heathernelly

Best ResponseYou've already chosen the best response.0i know i have to write like (x+1)(x2)(x+2)

dpaInc

Best ResponseYou've already chosen the best response.1standard form for a cubic polynomial is: \(\large y=ax^3+bx^2+cx+d \) where a, b, c, d are real numbers.

dpaInc

Best ResponseYou've already chosen the best response.1not quite... since the zeros are 1, 2, and 2, then the factors are (x1)(x+2)(x2)

dpaInc

Best ResponseYou've already chosen the best response.1so all you do is multiply out the 3 binomials....

Best ResponseYou've already chosen the best response.0how is it 1 when it says 1 ?

dpaInc

Best ResponseYou've already chosen the best response.1a zero refers to where the graph crosses the xaxis (when y=0) so the equation is 0 = (x1)(x+2)(x2) if x=1, you'll have 0 = (11)(1+2)(12) which is a true statement but if you have what you wrote down, 0 = (1+1)(1+2)(12) is not a true statement

Best ResponseYou've already chosen the best response.1multiply out the binomials: (x1)(x+2)(x2) = \(\large x^3x^24x+4 \)
