Review #16Given the function below evaluate each

functional expression

f(x) = 3x x2a) f(3)

b) 2f(x 3)



f(x) = 3x x2a) f(3)

f(x) = 3x x2b) 2f(x 3)

Review #17 Given the function below evaluate the functional expression given

f(x) = 3x x2 f(x + h) f(x) h

f(x) = 3x - x2

f(x + h) =

f(x + h) = 3(x + h) - (x + h)2

f(x + h) = 3(x + h) - (x2 + 2hx + h2)

f(x + h) = 3x + 3h - x2 - 2hx - h2


f(x) = 3x x2 f(x + h) f(x) h

(3x + 3h - x2 - 2hx - h2) - (3x - x2)h

3x + 3h - x2 - 2hx - h2 - 3x + x2

h

Answers to p 1981) It is possible they could have the same slope, yaxis has not been numerically labeled therefore my picture can be interpreted in many ways.2) The line with a slop of 4 is steeper. It has a value that is "larger" than 5/2.4) No it is not a func.
