Which of the following is the graph of y= - x + 1
1 answer:
Answer:
See picture below
Step-by-step explanation:
To graph properly, remember that:
- The y intercept of the function, is the value of the function when x=0, and tells (in this case y=1 is the intercept). Locate this point in the graph.
- The x intercept, which is the value of x when y=0 is x=1. Locate it in the graph.
- You now have two points of a straight line: join this two points and you would have done it!

Remember how the tangent function is defined as
Now where exactly are the vertical assymptotes? Well, where cosx = 0, because anything over 0 is undefined, and where a value is undefined, you are required to draw a vertical assymptote.
Now where exactly are the x interecepts? Well, where sinx = 0, because remember, an x-intercept is where y = 0, or where it crosses the x-axis, meaning where the tangent function is equal to 0.
So the x-intercepts are at where sinx = 0.
