The y-intercept can be calculated by replacing x by 0. Using x equal to zero in given equation we get answer equal to 2. Thus the y-intercept is (0,2).
Since the base of exponential function is greater than 1, the function is increasing.
The range of exponential function is set of All real numbers greater than 0.
Since no value of x makes the expression undefined, the domain of the function is set of All Real numbers.
So the correct options are: A, C, F
The guts of the table are ...

Of course, you know the answer after figuring the third line of the table.
The two numbers are 27 and 58.
_____
If the second number is odd, the result after subtracting 4 will not be divisible by 2. This lets you reject the 1st and 4th choices immediately. As for the second choice, twice 25 is 10 less than 60, not 4 less, so that choice can also be discarded.
Starting from the system of equations
you can use substitution to get
This identifies the 3rd selection as the appropriate one.
The mean is just the arithmetic average...
Sample A=8.1
Sample B=8.11
Both Samples=8.105
So Ryan would be closer to being correct given either of or both samples.
The parent function was moved left one and down five. It also opened up due to the 1/2
Answer:
(4x+3)^2 = 18
16x+9=18
16x=9
<u>x=9/16</u>
