PLEASE ONLY ANSWER IF YOU’RE SURE, AND EXPLAIN! THANK YOU!

The function f (x) = 2 • 5^x can be used to represent an exponential growth curve. Which of the following points is NOT on the curve?

(2, 20)
(1, 10)
(2, 50)
(3, 250)

(2, 20)

Step-by-step explanation:

To begin, we first would have to substitute the x values in the function to see if they are true.

Let’s take the first ordered pair as an example: (2, 20)

f(x) = 2 • 5^(x)

f(2) = 2 • 5^(2) = 2 • 25 = 100

It should be (2, 100) not (2, 20). Therefore, this is your answer. To make sure it is correct, I suggest plugging in the x-values of the other answer choices as well. They should all be true. I highly recommend it, so you could get a better understanding. Hope this helps! (:
