that's all it says :// :(

yes... but you need to calculate the derivative of f to find the relative max/min of the function.

isn't this for a calculus class?

oh... so you're allowed to use the max/min functions of a graphing calculator?

since 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:

it looks like you have a relative max at x=4 and a relative min at x=0

yeah, but that's not one of my options :(

the function you gave at the start does not coincide with those choices...

thats what it says in my homework

dpaInc Group TitleBest ResponseYou've already chosen the best response.1
i 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.

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

i'm sorry.... i'm absolutely sure of my answer here.. even the calculator verifies my answer.... is this the function we started with correct?

yes it is ..hmm :// :(

What is a cubic polynomial function in standard form with zeros 1, –2, and 2?

do you know how to multiply out binomials?
 2 years ago

heathernelly Group TitleBest ResponseYou've already chosen the best response.0
i know i have to write like (x+1)(x2)(x+2)
 2 years ago

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

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

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

how is it 1 when it says 1 ?
 2 years ago

dpaInc Group TitleBest ResponseYou've already chosen the best response.1
a 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

multiply out the binomials: (x1)(x+2)(x2) = \(\large x^3x^24x+4 \)
