### Question Description

Suppose that the functions s and t are defined for all real numbers x as follows: s(x)=x-1 t(x)=3x+5. Write the expressions for (t*s)(x) and (t+s)(x) and evaluate (t-s)(1)

## Final Answer

Thank you for the opportunity to help you with your question!

s(x) = x-1t(x) = 3x+5

A) ( s * t )(x) means to multiply the functions:

(x-1)(3x+5)= 3x^2 -5x -8
