Which point does NOT lie on the graph of y=2(5)xy = 2(5)^x?

A

(0,2)(0, 2)

B

(1,10)(1, 10)

C

(2,50)(2, 50)

D

(2,25)(2, 25)

Correct Answer: D

Choice D is the correct answer. Check each point.

  1. Choice A: x=0x=0, y=2(5)0=2y = 2(5)^0 = 2
  2. Choice B: x=1x=1, y=2(5)1=10y = 2(5)^1 = 10
  3. Choice C: x=2x=2, y=2(5)2=50y = 2(5)^2 = 50
  4. Choice D: x=2x=2, y=50eq25y = 50 eq 25

💡 Strategic Tip: Substitute each point into the equation to verify.

Choice A is incorrect because this point is on the graph. Choice B is incorrect because this point is on the graph. Choice C is incorrect because this point is on the graph.
