se show me the process of solving these functions with the work and steps show f(-4)=5 f(4)=-2 then what is the equation of the line? what does f(8)=?...

could someone please show me the process of solving these functions with the work and steps show

f(-4)=5 f(4)=-2 then what is the equation of the line? what does f(8)=?

T(-5)=-3 T(4)=1 what is the equation of the line? and what is the T(-4)
