h(x)

anonymous · Answer

it represent an AP with standard difference .25

anonymous · Answer

h(x) is the correct answer. The first two are exponential growth. The last one is exponential decay.

anonymous · Answer

not D either?

anonymous · Answer

yeah, D looks weird with that k(0) = 0... I'm thinking that's not an exponentional function either. You'd need k(0) = 1 for it to be true
