The question is incomplete. Here is the complete question:
Which of the functions have a range of all real numbers greater than or equal to 1 or less than or equal to -1? check all that apply.
A.
B.
C.
D.
Answer:
A.
D.
Step-by-step explanation:
Given:
The range is greater than or equal to 1 or less than or equal to -1.
The given choices are:
Choice A:
We know that, the
The range of is from -1 to 1 given as [-1, 1]. So,
Therefore, on removing the absolute sign, we rewrite the secant function as:
Therefore, the range of is all real numbers greater than or equal to 1 or less than or equal to-1.
Choice B:
We know that, the range of tangent function is all real numbers. So, choice B is incorrect.
Choice C:
We know that, the range of cotangent function is all real numbers. So, choice C is incorrect.
Choice D:
We know that, the
The range of is from -1 to 1 given as [-1, 1]. So,
Therefore, on removing the absolute sign, we rewrite the cosecant function as:
Therefore, the range of is all real numbers greater than or equal to 1 or less than or equal to-1.
Answer:
The answer is
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the point is (2, 4) and the slope is 3
The equation of the line is
We have the final answer as
