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

f(x) has no x-term.

Option 2.

Explanation:

Linear function are those whose graph is a straight line. A straight capacity has the accompanying structure. y = f(x) = a + bx. A direct capacity has one autonomous variable and one ward variable. The autonomous variable is x and the reliant variable is y.

A linear function is an arithmetical condition wherein each term is either a consistent or the result of a steady and (the principal intensity of) a solitary variable. A capacity is a connection with the property that each info is identified with precisely one yield. A connection is a lot of requested sets.
