f(x) = 5x² + 3

Explanation:

Exponential Function:
`a(b)^x+c`

Logarithmic Function:
`alog_bx+c`

5x² + 3 is a quadratic function. Therefore, it is not an exponential or logarithmic function and is incorrect.

log₅x is a logarithmic function. Therefore, it is correct.

5log₃x + 3 is a logarithmic function. Therefore, it is correct.

5ˣ + 3 is an exponential function. Therefore it is correct.
