Question

Choose the function whose graph is given below.

Answer 1

y= sec x

Explanation:

Answer 2

option C is correct, i.e. y = sec(x).

Explanation:

Given is a graph of a trigonometric function.

We have four choices to select from:-

A. y = cot(x)

B. y = tan(x)

C. y = sec(x)

D. y = csc(x)

We can check the y-intercept from the graph that is (0, 1).

Substituting x=0 in each option as follows:-

A. y = cot(0) = ∞.

B. y = tan(0) = 0.

C. y = sec(0) = 1.

D. y = csc(0) = ∞.

Hence, option C is correct, i.e. y = sec(x).
