Question

What is the output value for the following function if the input value is 4.5?y = 2x + 0.5options:259.524.5

Answer 1

Solution:

Given the equation below

$y=2x+0.5$

Where

$\begin{gathered} x\text{ is the input value} \\ y\text{ is the output value} \end{gathered}$

If the input value is 4.5, i.e. x = 4.5, the output value will be

$\begin{gathered} y=2x+0.5 \\ y=2(4.5)+0.5=9+0.5=9.5 \\ y=9.5 \end{gathered}$

Hence, the output value is 9.5
