How to create subtitute command for algebraic view because it only works in CAS view
Answered
I need to create a command similar to the substitute command where I have the expression of the function in terms of the variable x and the variable x in the expression I want to replace with expressions or values and that the output is in a text format.
f(x)=4x1
text1="f(a+b)=4(a+b)1"
text2="f(2)=4(2)1"
f(x)=2x^2+x+1
text1="f(a+b)= 2(a+b)^2+(x)+1"
text2="f(3)"=2(3)^2+(3)+1"

Variant as laTex (include custom tool)
convert f(x)=4x1 to text dragging it to graphics view
convert the text to unicode
substitute the unicode of x with the unicodes of (a+b)
then convert unicode to text
