Question

What is the domain of y = sec(x)?

1) all real numbers
2) all real numbers except π/2 + nπ, where n is any integer
3) all real numbers except 3π/2 + nπ, where n is any integer
4) all real numbers except π/2 + nπ and 3π/2 + nπ, where n is any integer

Answer 1

To find the ð‘¦-intercepts, substitute the slope and the coordinates of the given point into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦.

Step-by-step explanation:

To find the ð‘¦-intercepts of a line passing through a given point and parallel or perpendicular to another line, you would substitute the slope and the coordinates of the given point into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦. So the correct option is: 3) Substitute the slope and the coordinates of point R into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦.
