A function g is given by g(x) = x- - 7. g(x +h) - g(x) Find g( - 2). g(0), g(7), g(a +h), and g( - 2) = (Simplify your answer.1 A function f is given by f(x) = This function takes a number x, adds 5, squares the result, and takes the reciprocal of that result. (x +5)2 f(x + h) - f(x) Find f(2), f(0), f(a), f(x + h), and h Find f(2). f(2) = (Simplify your answer.)fix + h) - For f(x) = - 4x- - 3x - 4. find f(x + h) - f(x = hFor the piecewise function, find the values h( - 7), h(1), h(3), and h(7). - 3x - 10, for x
