there is not enough info. There must be more to the question.
Please help for f(x)^3 find in simplest form: (i) F(x) + 2
what is your f(x), what are the other options?
you should post a screen shot of the actual question.
fine i will post a scrren shot
is this clear enough
the first question
You should start off by plotting f(x)=x^3 first
ok, they are saying if you have the curve \[ f(x)= x^3\] write the equation of a new curve, that we get by adding 2: \[ F(x) = x^3 + 2\] and then they want you to graph both curves.
Then depending on what you add or subtract from f(x), we can accordingly shift our graph
Do you know how to graph \( y=x^3 \)?
and @Nishant_Garg how did u do tht
graph of x^3 will look something like |dw:1441712835820:dw|
how did u do x^3 + 2
ths wht the part i m confused in
why not 2x^3
Now if you add or subtract something from x^3, you just need to shift x^3 by that much on the y axis, if you add 2, shift the graph up by 2 units, if u subtract 3, shift down by 3 units and so on
you plot y= x^3 + 2 by finding (x,y) points and you are doing x^3 + 2 because the formula says f(x)+2 (not 2*f(x))
alright i get it yes. who should i medal
x y= x^3 + 2 0 0+2 = 2 1 1 +2 = 3 -1 -1 + 2 = 1 2 8+2=10 -2 -8 +2 = -6 plot the points (-2,-6) (-1,1) (0,2) (1,3) (2,10)
i get it thnxs but who should i medal
The whole point of this problem is to see f(x) and f(x)+2 have the same shape, but f(x)+2 is 2 steps above f(x)
who should i medal
It's ok I don't care
the also want you to plot y= x^3 - 3 and it looks like another curve ? they mention 4.
and they want you to figure out if you add +b to the function, it shifts it "up" b steps and -b shifts the function down by b steps
its simple x^3 - 3
it's simple if you know how to do it.
