Given f ( x ) = x ²

Question

Given f ( x ) = x ² - 7 x - 18 and g ( x ) = x - 4, find the following. ( f + g ) ( 0 ) A) ( f + g ) ( 0 ) = - 22 B) ( f + g ) ( 0 ) = - 18 C) ( f + g ) ( 0 ) = - 19 D) ( f + g ) ( 0 ) = - 4 E) Undefined

To find (f + g)(0), we substitute x = 0 into both functions and add the results. For f(0) = 0^2 - 7*0 - 18 = -18, and g(0) = 0 - 4 = -4. Adding these gives -18 + (-4) = -22.
