Answer:
Graph 2 is the cubic equation.
Step-by-step explanation:
We have been given the two graphs
So, we will conclude the function by end behavior
The cubic function enters from the left downwards and exists the graph from the right.
Cubic function will have 3 zeroes being of 3rd degree
And since the second function cuts the graph at three points
Hence, second graph is the cubic equation.
Zeroes are: -3 ,0 and 3.
Answer:
Step-by-step explanation:
The given equation is √2x+1+3=0
And we have been given that x= 4
I do not agree with the solution because it does not give any real solution. It only gives possible solution. If you plug the value 4 in the original equation you will get 8 and the square root of 8 is a complex number. Thus 4 is an extraneous solution....
Answer:
One pair of gloves costs $3.75.
Step-by-step explanation:
Systems of equations
x=hats y=gloves
2x+3y=28.25
x+y=12.25
2(12.25-y)+3y=28.25
24.5+y=28.25
y=3.75
Based on the function given, the domain of f(x) is -18 ≤ x ≤ 10 and the range is 16 ≤ f(x) ≤ 95
<h3>What are the domain and range?</h3>
The domain of a function is found by looking at a graph from left to right. This means that x will be equal to or greater than the smallest x value and less than or equal to the largest x value.
Domain is therefore:
-18 ≤ x ≤ 10
The range can be found by looking at the y value. The value if f(x) will be equal to or greater than the smallest y value and less than or equal to the largest y value.
Range is:
16 ≤ f(x) ≤ 95

Answer:A
Step-by-step explanation:
There is a pattern where every two days the previous log is multiplied by three. If you divide 3 by 2 you get 1.5 this is the increase per one day so just multiply day 6 by 1.5 to get the answer for day 7.
