I believe it would be the third option
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].
From the expression 2f + 5(8-f), we know that Karla caught f purple dot fish, and (8-f) green dot fish, because green dot fish gives 5 points.
2f -points for the purple dot fish, f is a number of the purple dot fish.
5(8-f) - points for the green dot fish, (8-f) is a number of the green dot fish.
So,
altogether she made 8 attempts.
One attempt cost 50 cents,
8 attempts cost 8*50=400 cents = $ 4.
Answer is B. 4 (dollars).
Answer:
No
Step-by-step explanation:
A right triangle's sides add up to 180 but adding 32, 60, and 68 only gives you 160. So, no. That triangle is not a right triangle.
I hope I helped ^^
