Given:
The graph of a downward parabola.
To find:
The domain and range of the graph.
Solution:
Domain is the set of x-values or input values and range is the set of y-values or output values.
The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.
Domain = R
Domain = (-∞,∞)
The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.
From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.
Range = All real numbers less than or equal to -4.
Range = (-∞,-4]
Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].
Answer:
A. B
B. C and D
Step-by-step explanation:
A: 2/3 * 7/7
7/7= 1 which is larger than 2/3
Answer:
x = 135
Step-by-step explanation:
The three triangles are similar.
144/y = y/81
y^2 = 144 * 81
y = 12 * 9
y = 108
81^ + 108^2 = x^2
x^2 = 18225
x = 135
The answer is C because you can only roll an 8 with a show of 6 when you roll 6 and 1 which gives 7 and 6 and 2 which gives 8
Answer:
Percentage of gold bangles is 66.6 and of silver bangles it is 33.3
Step-by-step explanation:
Given:
Number of gold bangles Mala has = 
Number of silver bangles she has = 
Total number of bangles = 
= 
We have to find the percentage of each type of bangles.
So,
Percentage of bangles = 
- Percentage of gold bangles.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
- Percentage of silver bangles.
⇒ 
⇒ 
Percentage of gold bangles, Mala has = 66.6 and of silver bangles it is = 33.3
