What is the range of the function f(x)=3/4x-3
kipiarov [429]

Answer:

(-∞,0)∪(0,∞)

Step-by-step explanation:

The domain of a function is wherever the y values exist.  The only time the y values dont exist in this function is when the denominator is zero.  So the denominator does not exist at x=0, because that is when 4x = 0.

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
loris [4]

Answer:

New\ Lengths = (14,21)

New\ Scale\ Factor = \frac{1}{7}

Step-by-step explanation:

Given

Rectangle:

Length = 2 in

Width = 3 in

Scale Factor = 7

Solving (a):

The side lengths of the new scale is calculated as follows;

New Lengths = Old Lengths * Scale Factor

New\ Lengths = (2,3) * 7

New\ Lengths = (2 * 7,3* 7)

New\ Lengths = (14,21)

Solving (b): To go back to the original length

Given that the initial scale factor is 7;

The new scale factor is the reciprocal of the old factor;

Hence;

New\ Scale\ Factor = \frac{1}{7}

The range of the function y = 2cos x is -2 ≤ y ≤ 2.
Vadim26 [7]

<u>Answer:</u>

The range of the function y = 2cos x is -2 <y < 2 .

<u>Step-by-step explanation:</u>

We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,

since ,

cos (x + 2π) = cos x

So, the range of the  function y = 2cos x is -2 <y < 2 .

Find the missing angle
inna [77]

THEOREM:

  • Angle sum property —: The sum of interior angles of a triangle is 180°.

ANSWER:

Let the missing angle be x.

By angle sum property,

  • ∠x + 20° + 80° = 180°
  • ∠x + 100 = 180°
  • ∠x = 180° – 100°
  • ∠x = 80°

So, <u>Correct choice</u> - [C] 80°.
