Question

What is the output value for the following function if the input value is 3.2?

y = 2 x - 1

A:1
B:2
C:4.2
D:5.4

Answer 1

For functions, there is only many input values, but there can be only one output value, and there can be no identical x values. For this, x=3.2. If y= 2*3.2 - 1, then y=5.4.
