function input(x)
Fw=0;
Fg=-12.9;
Bw=100;
Bg=197;
F=Fw+x*(Fg-Fw);
B=Bw+x*(Bg-Bw);
XX=x*100;
Line1_1='For an aqueous mixture of ';
Line1_2='glycol';
Line2_1='the freezing point is ';
Line2_2='Celcius and';
Line3_1='the boiling point is ';
Line3_2='Celcius';
fprintf(Line1_1 ,XX,Line1_2)
fprintf(Line2_1 ,F,Line2_2)
fprintf(Line3_1 ,B,Line3_2)
end
output: For an aqueous mixture of the freezing point is the boiling point is >>
Why is my function not including XX,B, and F in the output even though they are included in the fprintf functions? Just trying to figure out what code I'm missing to get the output to work correctly

In addition to the feedback about format specifiers in your fprintf calls that others have given you, I want to recommend that you change the name of your function because input already has a meaning in MATLAB.

Look at the examples for fprintf in the documentation. You need to include a format specification to include variable values.
x = 2.5;
input(x)
function input(x)
Fw=0;
Fg=-12.9;
Bw=100;
Bg=197;
F=Fw+x*(Fg-Fw);
B=Bw+x*(Bg-Bw);
XX=x*100;
Line1_1='For an aqueous mixture of %g ';
Line1_2='glycol ';
Line2_1='the freezing point is %g ';
Line2_2='Celcius and ';
Line3_1='the boiling point is %g ';
Line3_2='Celcius ';
fprintf([Line1_1, Line1_2], XX)
fprintf([Line2_1,Line2_2], F)
fprintf([Line3_1,Line3_2], B)
end
