Answer :

To determine the output value of the function [tex]\( y = 2x + 0.5 \)[/tex] for an input value of [tex]\( x = 4.5 \)[/tex], follow these steps:

1. Substitute the input value into the equation:
[tex]\[ y = 2(4.5) + 0.5 \][/tex]

2. Perform the multiplication:
[tex]\[ 2 \times 4.5 = 9 \][/tex]

3. Add the constant term:
[tex]\[ 9 + 0.5 = 9.5 \][/tex]

Therefore, the output value of the function for an input of [tex]\( x = 4.5 \)[/tex] is [tex]\( 9.5 \)[/tex].

Out of the provided options, the correct output value is [tex]\( 9.5 \)[/tex].
B. 9.5
all you have to do is plug it in
2(4.5)+0.5= 9.5
