help?
23. Which kind of function best models the data in the table? Use differences or ratios. x y 0 1.7 1 6.8 2 27.2 3 108.8 4 435.2 linear quadratic exponential none of the above
' Use differences or ratios.' did you try ratios ?
6.8/1.7 =.... ? 27.2/6.8=... ? ... 435.2/108.8=...?
yes i did just couldnt get the right answer
what ratio are you getting ?
6.8/1.7 =.. ?
13.6 : 3.4
whats that ? 6.8/1.7 =4 you'll get 4 for every y value/ x value so, you can write the equation as y/ (x-1) = 4 or y=4(x-1) is this linear or quadratic or exponential ?
oh wow i was going it completely wrong...
and quadratic
umm...no ..a quadratic equation has ^2 (2nd power/exponent) in it its not the case here.
umm... im not sure i know what im doing
you are trying to find what kind of model f(x) represents.
* y represents
y=4(x-1) is a linear equation.
im still lost.. lol sry
i tried ....is all i can say.
ok thx anyway.
good luck!
