The slope of the ladder making an angle 30 degree with the floor is dash​

Since, Ladder makes an angle 60

∘

with the floor as shown in figure.

∴ ladder makes 120

∘

angle with the positive direction of x-axis.

⇒ slope of ladder =tan120

∘

=tan(90

∘

+30

∘

)=−cot30

∘

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
