What makes this equation an exponential function? y=6x+4

it has variables

Step-by-step explanation:

Definition: "Exponential functions have the form f (x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent."

That's the definition I found online.

pretty sure its because it has an x, a y, and a variable!
