I need to find the domain and ranges of some of these graphs and I can’t really do the last few! Can anyone help?
hodyreva [135]
(1) For the parabola on the bottom row, the domain would be R and the range would be y ≥ -5

(2) For the hyperbola on the bottom row, the domain would be R\{3} (since there is an asymptote at x = 3) and the range would be R\{4} (since there is an asymptote at y = 4)

(3) For the square root function on the bottom row, the domain would be x ≥ -5 and the range would be (-∞, -2]

(4) For the function to the very right on the bottom row, the domain would be R and the range would be (-∞, -3]

Please include answer and explanation :))
Fiesta28 [93]

Answer:

<em>Domain={2,5,8}</em>

<em>Range={1,3,6}</em>

<em>Function: YES</em>

Step-by-step explanation:

<u>The Domain of a Function </u>

Is the set of values the input variable x takes.

<u>Range of a Function </u>

It's the set of values the output function takes when x moves into the function's domain.

A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.

Following the definitions above, the domain of the relationship is the set of input values:

Domain={2,5,8}

The range is the set of output values:

Range={1,3,6}

Since each element in the input set is related only to one element in the range, the given relationship is a function.

Answers:

Domain={2,5,8}

Range={1,3,6}

Function: YES

The difference between the acute angles of a right angled triangle is 72degree find them .
MaRussiya [10]

The 2 angles add up to 90 degrees so

x + y = 90, also:-

x - y = 72 (given)

adding the 2 equations:-

2x = 162

x = 81

and therefore

y + 81 = 90

y = 9


Answer the 2 angles are 81 and 9 degrees
