Hey there!
To figure out what "x" means, you can divide the numbers 126 and 14 . . .
126 divided by 14 = 9
9 x 14 = 126
9 = x
----------------
x = 9
----------------
Hope this helps you.
Have a great day!
Format: y = mx + b
m = slope, b = y intercept
The answer is y = x + 2
F(x)=IxI-5
when you shift it up, add the units to the end of y=IxI
when you shift it down, subtract the units to the end of y=IxI
50 is 46.82 rounded to the nearest ten
