Let f(x) = 9x − 1 and g(x) = 3x + 1. find the following.
(a) (f + g)(−2) =
(b) (f/g)(3) =
(c) (f − g)(0) =
(d) (f · g)(2) =

  (a) -24

  (b) 2.6

  (c) -2

  (d) 119

Step-by-step explanation:

It is convenient to let a calculator or spreadsheet do the function evaluations. That makes the composite functions easier to calculate.

(a) (f+g)(-2) = f(-2) +g(-2) = -19 +(-5) = -24

(b) (f/g)(3) = f(3)/g(3) = 26/10 = 2.6

(c) (f-g)(0) = f(0) -g(0) = -1 -1 = -2

(d) (f·g)(2) = f(2)·g(2) = 17·7 = 119

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
