Question

What is the output value for the following function if the input value is 3.2?y = 2x - 124.215.4

Answer 1

The Solution:

Given:

$y=2x-1$

We are asked to find the output when the input is 3.2

That is, find y when x = 3.2

$y=2(3.2)-1=6.4-1=5.4$

Therefore, the correct answer is 5.4 [option 4]
