sec(x)

Enter function:

  

---

With the function that you entered of sec(x), plot points, determine the intercepts, domain, range

Since you did not specify a qualifying variable or function notation in your expression, we will assume y
y = sec(x)

Determine function type:

Since we have one of the standard trigonometric functions:
this is a trigonometric function

Now Plot points from pi/6 to 2pi

Determine the y-intercept:

The y-intercept is found when x is set to 0. From the grid above, our y-intercept is 1.1547005383793

Determine the x-intercept

The x-intercept is found when y is set to 0
The y-intercept is found when y is set to 0. From the grid above, our x-intercept is 0

Determine the domain of the function:

The domain represents all values of x that you can enter
The domain is (-∞, ∞) or All Real Number

Determine the range of the function:

The range is all the possible values of y or ƒ(x) that can exist
The range is (-∞, 1) U (1, ∞)

You have 2 free calculationss remaining
