State whether each equation in Exercises 25–30 represents a linear,
quadratic, or exponential function. Tell how you decided.

3x^2=5

*I believe this equation is a exponential function but, I'm not sure how to explain it.*

  • MATH - ,

    The determinant factor is the exponent.

    If the variable is in the exponent, then it is exponential. For example,
    4x+1=10

    If the maximum value of the exponent is two, then the expression/equation is quadratic. For example:
    x²+3x+1=0

    If the maximum of the exponent is 1, or if exponents are absent (i.e. =1), it is linear. For example,
    4x+5y=3
