Answer:
x = 3/4
Step-by-step explanation:
f(x) = -2×2 +4x +1
f(x) = -4 +4x +1
f(x) = 4x -3
3 = 4x
3/4 = x
x= 3/4
There are 26 possible lowercase letters, 26 possible uppercase letters, and 10 possible numbers (0-9).
26+26+10=62
That means there's a 1/62 chance that they get one letter right.
But there's 15 letters.
They're chance would decrease each time to get it exact.
1/62 divided by 15/1 =
1/832
So there is a 1 in 832 chance that the hacker guesses it correct first try with that information.
I wish I can help but I’m bad at this sorry!
Answer:
left one is a function that is y=x
right is not a function
Step-by-step explanation:
the input is the same as the output no transformation is happening.
it cannot be a function because an x value of 8 cannot give a y value of 35 and 21 because it x values can't have multiple y functions in a function.
