|x| + ? f(x) = Answer: (0, ) Question 24 Graph y = |x2| 2x 8? − − Question 25 1 What is the value of f(x) = 81x ? when = x 2 Answer f(x) = 9 Question 26 Find the inverse of y = 3x 2 – get alone “x” Once you have "x =", switch x and y; the "y =" is the inverse. Then the inverse is = (x + 2) / 3 y Question 27 log What is the value of rounded to the nearest hundredth? 26 Answer: log 2.585 = ≈ ≈ 106 log 102
f(x) = |x| + ? Answer: (0, ) Question 24 Graph y = |x2| − 2x − 8? Question 25 What is the value of f(x) = 81x when x = 1 2 ? Answer f(x) = 9 Question 26 Find the inverse of y = 3x – 2 get “x” alone Once you have "x =", switch x and y; the "y =" is the inverse. Then the inverse is y = (x + 2) / 3 Question 27 What is the value of log 26 rounded to the nearest hundredth? Answer: = log 106 ≈ ≈ 2.585 log 102
