Consider the two functions. f x x 2 – 8x + 7
WebThe Sum of Two Functions Suppose we have two functions, f ( x) and g ( x ). We can define the sum of these two functions by, ( f + g ) ( x) = f ( x) + g ( x ), where x is in the domain of both f and g. For example, we can add the functions f ( x) = x2 − 1 and g ( x) = 2 x3 + 3 as, ( f + g ) ( x) = f ( x) + g ( x) = x2 − 1 + 2 x3 + 3 WebGiven f (x) = 2x, g(x) = x + 4, and h(x) = 5 − x3, find (f + g) (2), (h − g) (2), (f × h) (2), and (h / g) (2). This exercise differs from the previous one in that I not only have to do the operations with the functions, but I also have to evaluate at a particular x -value.
