Modeling with Trigonometric Expressions and Functions: Part Two — Test

Question 1

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?

Revolt · Accepted Answer

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.

Question 2

What is the equation of the given graph?

Revolt · Accepted Answer

y is equal to secant of open paren x minus 4 close paren

Question 3
