Q:

Is f(x)=x(x+5) a linear function?

Accepted Solution

A:
Answer:f (x) = (x+5) is linearStep-by-step explanation:We are given the following function and we are to determine if it is a linear function or not:[tex] f ( x ) = ( x + 5 ) [/tex]For a function to be linear, it must be written in the standard form [tex]y=mx+c[/tex] and its graph gives a straight line. Whereas, when an equation is squared, its graph becomes a curved one which is not linear.Therefore, the given function f (x) = (x+5) is linear.
