Answer:
B
Step-by-step explanation:
The black graph is the graph of y=f(x).
The red graph is the reflection of the black graph across the y-axis.
A. 
determines the translation of the graph 
one unit to the right.
B. 
determines the reflection of the graph across the y-axis.
C. 
determines the translation of the graph one unit up.
D. 
determines the reflection of the graph across the y-axis.
Answer:
2^2
Step-by-step explanation:
2^3 • 2^3 • 2^-4 = 4
and 2^2 = 4
Answer: A. 3
Step-by-step explanation: You can't put x and y together. There are two different variables. Then the 5, is just can't add together with another number because the numbers have a variable with it.
Please mark me brainliest bc one more to get a higher rank :)
A.
= (x + 2)^2 - 4 - 11
= (x + 2)^2 - 15
B. vertex is at ( -2, -15) which is a minimum because the coefficient of x^2 is positive.
C. The axis of symmetry is a vertical line passing through the vertex It is
x = -2.
Hi!
Let's write the equation in number form first.
7 over 8
7/8
minus 1
7/8 - 1
over x
7/8 - 1/x
equals 3
7/8 - 1/x = 3
over 4
7/8 - 1/x = 3/4
Now to find the value, let's put each option as the value for x.
A. x = 1
7/8 - 1/1 = 3/4
7/8 - 1 = 3/4
0.875 - 1 = 0.75
-0.125 = 0.75
This is wrong.
B. x = 2
7/8 - 1/2 = 3/4
7/8 - 0.5 = 3/4
0.875 - 0.5 = 0.75
0.375 = 0.75
This is wrong.
C. x = 4
7/8 - 1/4 = 3/4
7/8 - 0.25 = 3/4
0.875 - 0.25 = 0.75
0.625 = 0.75
This is wrong.
D. x = 8
7/8 - 1/8 = 3/4
7/8 - 0.125 = 3/4
0.875 - 0.125 = 0.75
0.75 = 0.75
This is correct!
The answer is d. x = 8
Hope this helps! :)
