Question

If f(x) is a linear function, which statement must be true?

f(x) has no constant term.
f(x) has no x2-term.
f(x) has no terms with a coefficient other than 1.
f(x) has no x-term.

Answer 1

f(x) has no x^2 term if it's a line. x^2 would be a quadratic

Answer 2

f(x) has not x^2 term.

Explanation:

Linear function is in the form of y=mx+b

In the linear function y=mx+b there is a constant term b

There is also an x term.

m is the slope of f(x). The value of 'm' can be any number.

If we have x^2 term in f(x) then it is quadratic function.

Linear function must always have x with exponent 1

True option is f(x) has not x^2 term.
