Is D correct?
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?

(12(2)^x-1)(3x)

18 points
384 points
4020 points
6912 points

Elise, your exponent is really not clear.  Please use the symbol  ^  to indicate exponentiation, and if you have a multi-part exponent such as n-1, please enclose it in parentheses.   Mind presenting this problem again?  Thank you.

mathmale · Answer

There's ambiguity in your "h(x) = 3x" also.  Did you mean "three times x," or did you mean "3 raised to the power x?"

Please clarify that also.

Is it 12*2^x

princeharryyy · Answer

Yeah it's right... Your power is x-1, 
So 12*2*2*2*2*2 *18 = 6912 correct
