I am thinking that it may be A
I'm actually not sure what it's trying to ask, hold on.
what would happened if you decreased x by 1... i think
x^2 would be a parabola when graphed, if you were to minus 1 to x^2, then the y-intercept of the graph would shift down by 1 unit
So it is A?
Won't be able to give an answer, not too sure about this topic, sorry man!
Uhhhhhhh.... I have had 5 people try this question.... Hahahaha. This sucks
do you understand it @Vocaloid ?
ok, if x is decreased by one, x becomes (x-1) what happens when you plug (x-1) back into f(x)?
it will move the parabola 1 unit to the right ?
I don't know.I really don't understand this
but i dont the option oO
A. f(x) will have a change of 1-2x B. f(x) will have a change of x^2-2x+1 C. f(x) will have a change of 2x+1 D. f(x) will have a change of x^2
OH IS IT D!?!?!? @Vocaloid
no... please do what I asked you to do...
no, please substitute (x-1) for x in the equation f(x)
no, please check the right side of the equation replace x with (x-1)
almost, you're forgetting the parentheses
right! now, try expanding (x-1)^2
that would make it B?!
great! so, the original equation is f(x) = x^2 the new equation is f(x-1) = x^2 - 2x + 1 what CHANGED? what do f(x) and f(x-1) have in common? what is different?
Sorry, no, the answer is not B, please keep trying
What makes x^2 different than x^2 - 2x + 1 what part is different about the second equation?
right! so which answer do you think it is?
hint: -2x +1 = 1-2x
I mean A!!
great! you got it!!!
