Determine whether the function is linear or quadratic. identify the quadratic, linear, and constant terms. f(x)=(3x-+5)

At first glance, it might be tempting to say this is a linear function, because we see linear terms (3x and –6x); however, these are multiplied together, so it's actually a quadratic. 

We need to expand the function (hint: use FOIL) to identify the terms.



The x^2-term, or quadratic term, is . The x-term, or linear term, is . The number term, or constant term, is –20.
