Identify in the following equation is quadratic or linear?
y=10^3x
According to what I understand this needs to be a quadratic equation, because it is in exponential form, and a linear equation does not use exponents am I right??

If you mean 1000x, it is linear. It is were quadratic, there would be an x^2 term.
I assumen that you don't mean 1000 to the 3x power

Actually it does say y=10^3x which confuses me a little bit, I research a little and I think that this could be an equation in exponential function is this right??
Thank you for answering so fast!!
