Question

A video game sets the points needed to reach the next level based on the function g(x) = 12(2)x − 1, where x is the current level. The hardest setting promises to multiply the points needed in each level according to the function h(x) = 3x. How many points will a player need on the hardest setting of level 6?
18 points
384 points
4020 points
6912 points

Answer 2

first step is to use g(x) to calculate the number of points on the easy setting

if x = 6 then 12(2)^x − 1 = ?

Answer 3

wait is the x an exponent? or is x - 1 the exponent?

Answer 4

Yes maams ^-^

Answer 5

hm that's weird I get an answer that isn't one of the choices :S

Answer 6

Hmmm, one second :O

Answer 8

this question isn't worded very well

when you plug in x = 6 into g(x) you get 384 but that's not the answer they're looking for since the hard setting triples the points

but when you triple 384 you get an answer that isn't in the choices :S

Answer 9

they want you to multiply the points from g(x) by 4x which means 384 * 3 = 6912 points

Answer 10

Oh okay :D so it was right!! I chose that answer but I wasn't sure at first o.o thank you!
