Modeling with Trigonometric Expressions and Functions: Part Two — Test
Question 21 • Precalculus
Suppose you want to transform the graph of the function y is equal to tangent of open paren x plus pi over 4 close paren into the graph of the function y is equal to negative tangent times open paren x plus pi over 2 close paren Which transformations should you perform?
Answer
A
Reflect the graph of the first function across the line y is equal to negative 1 , translate it pi over 4 units to the left, and translate it 2 units up.
B
Reflect the graph of the first function across the line y is equal to negative 1 , translate it pi over 4 units to the right, and translate it 2 units up.
C
Reflect the graph of the first function across the x -axis, translate it pi over 4 units to the left, and translate it 2 units up.
D
Reflect the graph of the first function across the x -axis, translate it pi over 4 units to the right, and translate it 2 units up.
