Given the function f(@) = 4x + 7, evaluate and simplify the expressions below. See special instructions on how to enter your answers. f(a) = f (a t h) = f(a + h) - f(a) h Instructions: Simplify answers as much as possible. Expressions such as 4(@ + 2) and (x + 5)2 should be expanded. Also collect like terms, so 3x + @ should be written as 4x. . Question 5 A Let f(x) = 4x + 2 and g(x) = 2x' + 3x. After simplifying, (f o g) (x) =Question 7 A If f(x) = = + 1and g(x) = x - 1 (a) f(g(z)) (b) g( f (=) ) = (c) Thus g(@) is called an function of f(=). Question 12 The graph below is the function f(x) -5 -4 -3 -2 1 2 3 4 5 -2 Q3 Find lim f(I) Find lim f(x) Find lim f(I) Find f( - 1). Question 13 The graph below is the function f() -5 4 3 2 -1 2 3 4 Find lim f(z) C-2 Find lim f(E) Find lim f(x) Find f(2)> .
