Question

the points (0,1), (1,5), (2,25), (3,125) are on the graph of a function which equation represent that function

Answer 1

f(x) =
`5^(x)`

note the range is {1, 5, 25, 125 } which can be expressed as

{
`5^(0)`,
`5^(1)`,
`5^(2)`,
`5^(3)` }

the exponents being the domain { 0, 1, 2, 3 }

thus f(x) =
`5^(x)` an exponential function
