Question

f(x)=4x-3
A) Is the function f an odd function?
B) Is the function f a linear function?
C) Is the range of f (-∞,∞)?

anonymous · Answer

A)  Not odd.  The sum of an even function and an odd function is neither.  4x is odd, -3 is even.

B)  The function is linear, of the form y=mx+b.

C)  Both the domain and range of this function are the set of all real numbers.
