Answer:
x is greater than or equal to -7 but less than 9.
Step-by-step explanation:
Find the lowest and higest points on the graph.
Remember the domain is on the x - axis.
The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.
The next step is that the graph is getting larger so it is greater than or equal to.
On the other side of the graph do the same but it is less than not equal because the dot is open.
So foil
2y² +8y -y-4 = 2y²+7y-4
Answer:
The answer to your question is Domain (-∞, ∞) Range [-4, ∞)
Step-by-step explanation:
The Domain is the set of all possible values of the independent variable (x).
The Range is the set of all the possible values of the dependent variable when substitute the domain in the function.
On the graph, we find the domain looking at the x-axis
On a graph, we find the range, looking at all the y-axis
In this graph, x has values from -infinite to infinite, then, the domain is (-∞, ∞).
In this graph, y has values from -4 to infinite, then, the range is [-4, ∞)
The principle SQRT of 100 would be 10 because 10*10 is 100
Answer:
subtract from both sides and then multiplying both sides
Step-by-step explanation:
how can you solve y = -2x + 25 by subtraction
