Question

I really need help. Any help is appreciated.

Which ordered pairs lie on the graph of the exponential equation ​​ ​​ f(x)=4(5)2x ?

Select each correct answer.

​​ (−1,425)

​ (0,0)

​ (1,4)

​​ (2,2500)

Answer 1

The equation is:

`f ( x ) = 4 * 5 ^(2x)`
f ( - 1 ) = 4 * 1/25 = 4/25 ( false )
f ( 0 ) = 4 * 1 = 4 ( false )
f ( 1 ) = 4 * 25 = 100 ( false )
f ( 2 ) = 4 * 5 ^4 = 4 * 625 = 2500 ( correct )
Answer:
D ) ( 2, 2500 )
