Question

A video game sets the points needed to reach the next level based on the function g(x) = 7(3)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) = 4x. How many points will a player need on the hardest setting of level 4?

Answer 1

Is g(x) supposed to be 21x - 1 or
\[g(x)=7(3)^x-1\]

Answer 2

the second one

Answer 3

You need to find g(h(x)).

Answer 4

More specifically g(h(4))

Answer 5

g(h(x)) = 7(3)^(4x) - 1
= 7(81)^x - 1
