Answer 1

None of the functions listed represent an exponential function. The given functions are:

1. \( y = 6x^2 \) - This is a quadratic function.
2. \( y = 9x \) - This is a linear function.
3. \( y = -3x^2 + 2 \) - This is another quadratic function.
4. \( y = 7x \) - This is also a linear function.

An exponential function generally has the form \( y = a \cdot b^x \), where \( a \) is a constant, \( b \) is a positive constant (the base), and \( x \) is the variable in the exponent.

If you need to write an actual exponential function, you might consider something like \( y = 2^x \) or \( y = 3e^x \).
