Formative Quiz - Functions Operations Use the following information to answer the next 3 questions. Use the table to determine each value below 1. The value of 2. The value of ( g f )( 5 ) is ___ ( f g g − + )( 6 2 (1) ) is ___ 3. The value of ( + )(3) �� �� is ______ Use the following information to answer the next 2 questions The graphs of = ( ) �� �� �� and = ( ) �� �� �� are shown below 4. The value of ( f g )( 2 ) is ___ 5. Five operations are listed below. The two operation numbers for which the answer is undefined, are ____ and ____ 1 2 3 4 5 6 (0) �� (1) �� (0) ∙ �� (−1) �� (0) + �� (−1) ��
(0) �� (1) �� (0) �� (−1) �� (0) �� (−1) �� Use the following information to answer the next question Three functions are listed below f x x ( ) = − + 5 7 , ( ) g x x x = − + 3 8 , h x g x f x ( ) = − ( ) ( ) 2 The equation y=h(x) can be written in the form ( ) 2 h x ax bx c = + + 6. The values of b and c are shown in Row Row b c A. 2 1 B. -2 -1 C. -8 1 D. -8 -1 Use the following information to answer the next question h x f g x ( ) = • ( ) ( ) given that f x x ( ) = − − 2and g x x ( ) = + 2 1 , and Tavon graphed h x ( ) in interval notation the he correctly stated the range of 7. The range is
A. [− 5 4 , ∞) B. [ 9 8 , ∞) C. (−∞, − 5 4 ] D. (−∞, 9 8 ] Use the following information to answer the next question ( ) f x ( ) f x x ( ) = − 5and 2 ( ) g x x x = − − 3 10and Brayden sketched = h x ( ) g x 8. The domain and range of = ℎ( ) �� �� are shown in row Row Domain Range A. { | ≠ −2, �� �� } ������ { | ≠ 0, �� �� } ������ B. { | ≠ −2, �� �� } ������ { | ≠ 0, �� �� �� 1 7 , } ������ C. { | ≠ −2, �� �� �� ≠ 5, } ������ { | ≠ 0, �� �� } ������ D. { | ≠ −2, �� �� �� ≠ 5, } ������ { | ≠ 0, �� �� ��
