If y=50(3)xy = 50(3)^x, what happens to yy when xx increases by 1?

A

It increases by 3.

B

It is multiplied by 3.

C

It increases by 50.

D

It is multiplied by 50.

Correct Answer: B

Choice B is the correct answer. The base 3 is the multiplier.

  1. Concept: Exponential growth means multiplying by the base bb for each step.
  2. Identify: b=3b=3.
  3. Conclusion: yy is multiplied by 3.

💡 Strategic Tip: Exponential functions are about multiplication, not addition.

Choice A is incorrect because adding 3 would be linear. Choice D is incorrect because 50 is the initial value.
