Question

Which function is graphed below

Answer 1

I think the answer is a. f(x)= cos(x).

Answer 2

Answer: Option 1 is correct.

Step-by-step explanation:

This graph shows that it cuts x-axis at
`\frac{\pi} {2}`=0 and at
`\frac{3\pi} {2}`=0 which is satisfying the property of cosx

Extrema of the graph at x=0,
`\frac{\pi} {2}`,
`2\pi`

Properties of the given graph:

maxima at x=0 and
`2\pi`

minima at x=
`\pi}`

x-intercept at x =
`\frac{\pi} {2}`,
`\frac{3\pi} {2}`

period =
`2\pi`

Range [-1,1]

Domain is all real numbers.

These all properties follows by cos x function.

So, the given graph would be of cos x

Thus, Option 1 is correct.
