"Given that f(1) = 9, f'(1) = 5, g(9) = 6 and g'(9) = 4, what is the approximate value of g(f(1.05))?"

Can sage be used to solve the following kind of problem?

You can just use the following script to do it. You construct two functions f and g such that they have a slope of 5 and 4 respectively and add a constant such that f(1) = 9 and g(9)=6 then evaluate at 1.05 using g(f(1.05)).

```
f(x)=5*x+4
g(x)=4*x-30
g(f(1.05))
```
