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.
Step-by-step explanation:
Answer:
56.700
Step-by-step explanation:
1lb
125lb ≈ 0.45359237kg
xkg
Now, we cross multiply to solve for our unknown x:
x kg ≈ 125lb
1lb * 0.45359237 kg → x kg ≈ 56.699 kg
Conclusion: 125 lb ≈ 56.699 = 56.700 kg
