In Quadratic Equation Which Is the Linear Term?

A quadratic function is a function of the form f(x) = ax2 +bx+c, where a, b, and c are constants and a = 0. The term ax2 is called the quadratic term (hence the name given to the function), the term bx is called the linear term, and the term c is called the constant term.

How do you find the linear term?

A linear term has a degree of 1. For example, 5x, -2x and x are all linear terms. These terms are x to the first degree (X1), where the “1” isn't written (because any number to the first power is just that number). Terms that are not linear are called non-linear terms.

How can you tell if a quadratic equation is linear?

By finding the differences between dependent values, you can determine the degree of the model for data given as ordered pairs.
  1. If the first difference is the same value, the model will be linear.
  2. If the second difference is the same value, the model will be quadratic.
