If f(x) is a linear function, which statement must be true?
a.fx) has no constant term
b.f(x) has no x_term.
c.f(x) has no terms with a coefficient other than 1.
d.f(x) has no x-term.​

Respuesta :

The statements look all false:

  • A linear function can have constant terms, which is the b coefficient in the expression y=mx+b. For example, y=3x+5 has a constant term 5
  • A linear function has a x term. In the same example as before, 3x is the x term
  • The coefficients can be different from 1. In the example before, the x coefficient is 3 and the constant term is 5.
  • This looks like option b. Maybe there was a typo, and either b or d must be true.
