The function rule is y=2x-1 if the input is 3 what is the output? Please Help
well, plug in your value
y = 2*3 - 1 = ?
If my function rule is y=2x+1 what is the output of the input is -3?
To find the output of a function when the input is given, you need to substitute the given input value into the function and evaluate it. In this case, the function is defined as y = 2x - 1 and the input is given as 3.
To calculate the output, you need to substitute x = 3 into the function:
y = 2x - 1
y = 2(3) - 1
y = 6 - 1
y = 5
Therefore, when the input is 3, the output (y) is 5.
I still don’t get it
Is it 7
2*3 - 1 = 6-1
still think it's 7? really?
