does the rule y=-3x^5 represent an exponential function
Isn't the 5 an exponent?
No, the rule y = -3x^5 does not represent an exponential function. It is actually a polynomial function.
An exponential function is of the form y = a * b^x, where 'a' and 'b' are constants. In this case, we don't see any exponent involving 'x' or any base 'b'. Instead, we have a polynomial expression, -3x^5, which is a monomial of degree 5 (since the highest power of 'x' is 5).
