You only add up the exponents when you multiply.
Answer:
The 4th graph
Step-by-step explanation:
To determine which graph corresponds to the f(x) = \sqrt{x} we will start with inserting some values for x and see what y values we will obtain and then compare it with graphs.
f(1) = \sqrt{1} = 1\\f(2) = \sqrt{2} \approx 1.41\\f(4) = \sqrt{4} = 2\\f(9) = \sqrt{9} = 3
So, we can see that the pairs (1, 1), (2, 1.41), (4, 2), (3, 9) correspond to the fourth graph.
Do not be confused with the third graph - you can see that on the third graph there are also negative y values, which cannot be the case with the f(x) =\sqrt{x}, the range of that function is [0, \infty>, so there are only positive y values for f(x) = \sqrt{x}
Answer: A
<u>Step-by-step explanation:</u>
Create a table for y = x when x ≤ -1 and y = -x when x > 1.
Then, compare the coordinates from the table to the graph. The first graph, <em>which I consider to be graph A</em>, matches the coordinates from the table.
Answer: 24.0825%
Step-by-step explanation:
8.25% as fraction: 33/400
24+33/400
Convert element into fraction: 24x400/400
24x400/400+33/400= 9633/400
Final step: Make it into a decimal
<em><u>24.0825% is your answer</u></em>
