Answer:
A. 
Step-by-step explanation:
We are given the expression, 
On re-writing the expression after borrowing 1, we have,
= 
i.e. = 
i.e. =
Thus, the equivalent expression after borrowing 1 from the given expression is .
Hence, option A is correct.
For this function we can find y-intercept.
x=0, y=-2
This graph is on the top, right.
The third graph represents the data because the values in the table are identical to the ones plotted on that graph.
I think maybe the second one I’m not fully sure but I hope this might help
Basically y would be whatever the number x is times 2, so -2 to the second power is -4, -1 to the second power is -1, 0 to the second power is 0, 1 to the second power is 1 and 2 to the second power is 4. now all you have to do is graph those points and you’re good!
