I think it is C, am i right?
Which of the following options results in a graph that shows exponential growth?
f(x) = 0.4(0.2)x
f(x) = 4(0.98)x
f(x) = 0.7(5)x
f(x) = 5(4)−x

Best ResponseYou've already chosen the best response.1Rule: If you have \[\Large f(x) = a*(b)^x\] f(x) will have exponential growth if `b > 1` or f(x) will have exponential decay if `0 < b < 1`

Best ResponseYou've already chosen the best response.0so it is neither C or B..

Best ResponseYou've already chosen the best response.1Flip things around If you have \[\Large f(x) = a*(b)^{x}\] f(x) will have exponential decay if `b > 1` or f(x) will have exponential growth if `0 < b < 1`

Best ResponseYou've already chosen the best response.1which function has `b > 1` ? and has `x` (not `x`) in the exponent?

Best ResponseYou've already chosen the best response.1in choice A, what are the values of a and b?

Best ResponseYou've already chosen the best response.1for `f(x) = 0.4(0.2)^x`, the value of a and b are a = 0.4 b = 0.2 agreed?

Best ResponseYou've already chosen the best response.1adjust the sliders for 'a' and 'b'. Make sure 'a' stays as a positive number
