Answer (2)
c(x)=9x+27 is the function written using the distributive property
By applying the distributive property to the function c ( x ) = 9 ( x + 3 ) , we rewrite it as c ( x ) = 9 x + 27 . This involves multiplying each term inside the parentheses by the number outside. Therefore, the final form is 9 x + 27 .
