Answer:
Alicia ran 12 miles.
Step-by-step explanation:
They said that Nara ran 14 miles and she had ran 2 more than Alicia, so that would be 14 - 2 which is 12.
(3x-5)(2x-7)
6x^2 - 21 x -10x +35
6x^2 -31x +35
The first one
x= +7 or x=2-7 let me know if you need an explanation <3
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].
