Question

Which function represents exponential growth y=f(x) y=h(x) y=g(x) y=k(x)

Answer 1

Answer:

B. $y=h(x)$

D. $y=k(x)$

Step-by-step explanation:

We have been given a graph which represents 4 exponential functions and we are asked to choose which functions represent exponential growth.

Since we know that graph of an exponential growth function is always increasing. The rate of growth starts slow and increases rapidly as x increases. This means an x increases y values approaches positive infinity.

We can see from our given graph that as x becomes more and more positive our functions $y=f(x)$ and $y=g(x)$ are decreasing, while functions $y=h(x)$ and $y=k(x)$ are increasing and approaching to positive infinity.

Therefore, functions $y=h(x)$ and $y=k(x)$ represents exponential growth and options B and D are correct choices.
