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?

i know how to do it on a calculater ..but i left it at a friends house ://

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

heathernelly Group TitleBest ResponseYou've already chosen the best response.0
yeah, but that's not one of my options :(
 one year ago

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

thats what it says in my homework
 one year ago

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

but that's none of the options ://

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 :// :(

do you think you could help me with another one?

there has to be an error in those choices... yw... :)

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

do you know how to multiply out binomials?
 one year ago

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

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

heathernelly Group TitleBest ResponseYou've already chosen the best response.0
how is it 1 when it says 1 ?
 one year 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
 one year ago

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