Answer:
( f h ) (x) = 6 x² - 1
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given<em> f(x) = 3 x - 4</em>
g (x) = −x²+2 x−5
<em> h (x) = 2 x² + 1</em>
j (x) = 6 x + 2 - 8 x
K (x) = 3 x² - x + 7
<u><em>Step(ii)</em></u>:-
<em>( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )</em>
= 3 (2 x² + 1 ) - 4
= 3 ((2 x² ) + 3 - 4
= <em>6 x² - 1</em>
<u><em> Final answer:</em></u>-
∴ <em> ( f h ) (x) = 6 x² - 1</em>
6x-30 is equivalent to the expression
Make a 4x4 table where rows are Alice, Bart, Pamela, and Robert, and where columns are the professions: Dentist, Laywer, Teacher and Writer.
Start crossing out possible pairing person-profession using the facts given. When a job is clearly assigned, you can cross it off for the rest of the people, for example, Pamela is a dentist so none of the rest are a dentist (because we are told they have all different jobs).
Eventually your table becomes filled.
Alice is a Lawyer
Bart is a Writer <<< so this is choice (B) for your answer
Pamela is a Dentist
Robert is a Teacher
