Which of the following expressions is equal to ⁡tan⁡(-20°)? tan(20°) -tan(20°) cot(-20°) cot(20°)

B.

Step-by-step explanation:

We have been given an expression . We are asked to find the equivalent expression to our given expression.

We know that tangent is an odd trigonometric function and it is symmetric about the origin.

A function is known as an odd function, if   and it is symmetric with respect to origin.  

Since tangent is an odd function, therefore, and option B i the correct choice.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
