pre-calculus weird sheet...
Using the mapping formula, map the following point on the graph of y=x^3 onto the corresponding graph of y=5(x-7)^3-2.

what's the mapping formula thow??
OpenStudy (yumyum247):
a) 0,0
b) 1,1
c) 2,8
d) -2,-8
Parth (parthkohli):
"map the following point"
I don't see any point following that sentence.
OpenStudy (yumyum247):
scroll down homie
Parth (parthkohli):
Are those the choices, or do you have to work with each point?

no those are the points am suppose to plot on the graph
OpenStudy (yumyum247):
is it a translation thing question?
OpenStudy (thebrainzzzzz):
I think C. but i might be wrong :P
OpenStudy (yumyum247):
wut?^

Let's write the equation like this:\[y+2 = 5(x-7)^3\]Or like\[y+2 = (5^{1/3} x - 5^{1/3}\cdot7)^3\]This may look confusing, but you may be starting to se the similarities with the original equation.
OpenStudy (thebrainzzzzz):
lol
OpenStudy (yumyum247):
hold up let me draw it for you parth bby
Parth (parthkohli):
You don't even need to draw it, really.
It's just clear that both graphs are gonna be translated and stretched out in a weird manner.
