Chapter 6.4, Problem 55E

Function Arithmetic

Let f(x)=x2+5.5x+722  Which of the following is equal to f(x+h)−f(x)?

3) Use the functions f(x)= 12 - 2x and g(x) = 4x² – x – 7 to evaluate the following: a) f(4) b) f(-2) c) g(-5) d) g(h)

Pls help ASAP on all

19. Evaluate the difference quoatient: as much as possible: a.) f(x) = 2x + 7, f(x+h)-f(x) h b.) f(x) = 2x² + x for each of the following functions. Then simplify d.) f(x) = // I c.) f(x) = 3x² e.) f(x) = 2+x

Evaluate the function f(z) = 2z - 7 at the indicated values. a) Find f(z + 1) b) Find f(z + h) a) f(z+1)= b) f(z + h) = (Simplify your answer. Do not factor.) (Simplify your answer. Do not factor.)

Consider f(x) = 9x – 8. a. Compute: f(a) = b. Compute and simplify: f(a + h) c. Compute and simplify: f(a + h) – f(a) = f(a + h) – f(a) d. Compute and simplify: h
